Type of product: GAN GA/GA+.
Car: Porsche 996 911
Advantages:
Changes the personality of the car in a very positive way. Once you have driven the car with this product you will find it hard to use the car without it. That’s a genuine statement, I’ve tried it!!

Always has to be in the OBD socket. Not enough options, just dynamic or economical.
Comment:
Great product at a very good price.

Type of product: GAN GA/GA+.
Car: 2004 Porsche 996 C4S Tip
Advantages:
My car is normal aspirated and there are less products than for turbos , which give additional power other than remapping which is costly and limited. GAN is the only one which I can find for my car , easy and best. GAN+ offers Installation is ' Plug in OBD2 ' ONLY ! Extension cable works. 5 yr warranty 2 yr engine warranty up to 3000 euros Easy app control to get back to normal Can be used for 5 different cars +20HP and +30Nm claimed I installed it and drove more than 120km as instructed. First thing I felt was the less hesitation at uphill drive at a rather lower rev like 1200-1500 rpm . Torque at low rev got fatter I feel. Mine has a PSE with X-PIPE, and the sound at 4000+ rpm is really awesome. GAN GA+ is a very rare item for non turbo naturally aspirated vehicles like Porsche 996 Carrera. Remapping is something costly and not easy to get back to factory setting. GAN GA+ is very easy to install , just plug the device to the OBD2 coupler , and can choose mode from 3 (DYNAMIC,STOCK,ECO ) via smart phones. Extension cable worked nicely for my car. Nothing to worry ! ( video 3 ) Not sure about the actual number of maximum power / torque increase , but the first I noticed is the fatter torque at the lower rev like 1200-1500 rpm.(video 4 ) It got much more flexible driving uphill at this rpm range , hesitation has gone , where this kind of engine is not good at. Mine has the PSE with X-PIPE and sounds very nice at 3000+ rpm ( Video 5,6 ). Due to other traffic , it's not the full acceleration , but I can feel the quicker response of the engine.
Disadvantages:
Nothing yet. Hopefully forever.
Comment:
5 year warranty and 2 year engine warranty is very helping. I'd like to see the actual dyno data , even not 996 one but some other examples.

Type of product: GAN GA/GA+.
Car: KIA Cerato 1.6i
Advantages:
Very simple installation. A simple and comfortable mobile App. Real increase in power in Dynamic mode. And even in ECO mode, the car runs faster with less fuel consumption.
Disadvantages:
Disadvantage is that it takes a couple of minutes to switch from mode to mode. It’s impossible to switch quickly between modes (from ECO to Dynamic). There are no more bad for me.
Comment:
After Gan installation, I immediately tried the Dynamic mode. I got everything what I needed, the response of the acceleration pedal became better. I have 37 wheels size (regular 33) on the car, when I accelerated or went uphill, I felt that the car was going hard, now this isn’t so. Before purchasing this product I watched a lot of video in YouTube with pros and cons. after installation it is necessary to drive 120 km for the better adaptation of the device. As for me, so I got exactly what I wanted from Gan, the failure disappeared when I accelerate under load. Someone can say that the same result can be achieved with the Jeter acceleration pedal, but I had some experience with it and it didn’t give such me result as Gan did. Generally, I advise Gan to everyone who wants to get more positive emotions from his car.

Type of product: GAN GA/GA+.
Car: Dodge Challenger SR8
Advantages:
After installation, I went for a test drive and I felt a huge difference driving. My car is smoother and even faster that it already is. I truly recommend GÄN Chip Tuning for all muscle cars.
Disadvantages:
My Huawei P30 Pro couldn't detect the chip via the Gän app. Fortunely for me, my iPad detect the chip in no time and could install the software without worries.

Car: Opel Corsa D 1.4i 90hp
Advantages:
now my car has the power it deserves. before I had GÄN my car stopped pulling at 5000 rpm and now it is pulling up to the red line. and when I took my friends in the car my car was very slow due to the weight but now it accelerates much faster. and the app is very easy and you can choose from different driving styles.
Disadvantages:
my car uses more fuel but that was to be expected
Comment:
i love it a lot and especially for the price

Type of product: GAN GA/GA+.
Car: 2012 Audi A6 2.8 v6 Fsi
Advantages:
This device woke up the vehicle...the car felt very responsive and sharp...mid range power was alot better....highway cruising was a breeze....this product..really delivered. Switching of driving modes. Ability to use on different vehicles. Low risk tuning device. Warranty was a big deal for me. Great price. Quality product amd value for money vs other tuning options. Must have product for natural aspirated vehicles especially V6 and a drop in high performance air filter combo.
Disadvantages:
Shipping took a little while...understandably due to the Covid-19 affect on shipping and delivering to outside of Europe
Comment:
Customer service was great..I would highly recommend this high quality low risk high reward product.... I highly recommend this product...it delivers

Type of product: GAN GA/GA+.
Car: Toyota Auris Hybrid
Advantages:
Engine works better. Good torque between rpms, It breathes better. Every Mode has gained.
Disadvantages:
Nothing until now.
Comment:
The car feels more torquey, even at very low rpms ! Thing that I thought impossible for this peculiar engine. Power at high rpms is for real, I can climb up to 2000 meters high in the mountains easily now, car has lost its low breath. In Eco mode I can drive in tranquility @ 70 km/h, thing that was rather difficult before ! I am super satisfied .

Type of product: GAN GA/GA+.
Car: Honda civic, mk8, saloon, 1.8, R18
Advantages:
I am very happy with the increase in power in my, the car rides a lot more fun, the acceleration is more sharp, more torque feels as well, especially on low rpm . The engine runs more smoothly, has become more sporty, the sound changes slightly at high speed. Installation is very simple, download mobile app, connect device to car obd, drive 120km and the car changes obviously. Change app program is very simple, but I use only dynamic and very happy.
Disadvantages:
No disadvantages
Comment:
Hello everyone. I have a honda civic mk8 saloon 1.8 R18 engine. I was always skeptical of power chip tuning for an atmospheric engines. Turbine engines are easy to modify, but not atmospheric, I always thought. I have approached several tuning companies to increase the power of my car, but all in response do not work with such engines. I was skeptical about the power tuning chips. But I found the Gan tuning company page, studied the reviews and decided to give it a try. I ordered Gan +. They shipped very fast, in a few days. I installed it very easily and have using it already for months. And what can i say: I was surprised, my car really changed. The power and torque increased sharply. I can't tell you exactly the power and torque has increased how much manufacturer told because I haven't measured the power of the car before and after installation , but I think it's both increased or close to the truth. If you want to cheaply increase the power of your car, do not hesitate to buy Gan +. I highly recommend. Thanks for Gan Tuning.

Type of product: GAN GA/GA+.
Car: Toyota Aurion
Advantages:
1. Response of car feels better 2. Feels like there has been an increase in extra power and torque 3. GA+ bluetooth capability 4. Factory Auto set up is easy and takes out the guess work.
Disadvantages:
1. Instructions are easy for set up but there are no real instructions on how to use the custom/adjustment mode(s). I don't want to use guesswork so leaving the custom modes alone. Could Gan provide some detail instructions on the custom setup? Probaly won't need it, the factory settings have made a huge difference, just curious. 2. I also can't change the name of my vehicle on the app once installed without installing again which will take away one extra of my five original installs. I forgot to name my vehicle originally and it has given a default name. if Gan reads this, maybe there is a way to change my vehicle name once installed, please?
Comment:
I feel this product works. My car actually felt like it had less power when I first installed it, I was initially nervous about this. I know it needed some driving to calibrate properly, as per the Gan instructions. After driving to Cooma and back to Canberra, 200 plus km's, I noticed a definite improvement in response and power. Over the next two days of driving my normal routes around the city, it really settled in. The car drives and feels great. My car was powerful before but this has certainly made the power and torque more crisper. The six speed transmission changes better as well. I'm definitely leaving it my car, it's a fairdinkum great product, thanks Gan.

Car: Porsche 911 3.8i 355 hp
Advantages:
Simple installation, it really works, fuel saving - more than 1L/100 km, mobile App works perfectly in the city and outside! The car became faster. Gear changes also became faster. In the cabine it is much quieter due to the reduction of revs.
Disadvantages:
I haven’t noticed yet!

Car: Jeep Grand Cherokee 6.1i 426 h.p
Comment:
The installation took about 15 minutes, it really works, although I really did not believe in it. The car runs much softer in different modes and revs on the highway was lower than usual and I suppose the fuel consumption is also less, but at this moment I have no measurements. I am very glad with this purchase. I hope that in the future there will be no problem with it.

Car: BMW 7 Series E65 745i, 333 hp
Advantages:
After first minutes of using, the engine thrust increased, I can notice a better response of the acceleration pedal, and the fuel consumption decreased (about a liter) .

Type of product: GAN GA/GA+.
Car: Ferrari 458 Italia 4.5i, 570 h.p
Advantages:
The response of the acceleration pedal is better, there are no failure, no jerks. You don’t need any special skills for the installation, plug-in system, it’s easy to download App.
Disadvantages:
Switching from mode to mode via your smartphone requires a reboot within 3 minutes. Perhaps I didn’t fully understand its operating way. I have been using it only within 5 weeks, so 5 points!
Comment:
I can’t say anything about fuel consumption yet, but I can estimate that it is less about 2 l, but I am not sure. It is necessary to use it within 1-2 month and then I can speak about exact data.

Car: Porsche 911 (996) 3.6i
Advantages:
Simple and convenient. Satisfied with result.
Comment:
I connected this device via the attached cable and hid it behind the pile floor covering. Up to 100 km, I notices the result: the throttle response at 1,2,3 gear is better, the fuel consumption did not change (I use the “Dynamic” mode). I think the result is good for such kind of tuning. I like my car more.

Car: Stinger 3.3 T, 375 h.p.
Comment:
I purchased the most expensive version of this electronic miracle, I can say that the effect is very good (especially when pull away), the car began to drive much faster especially up to 120 km/h, then it gets worse, but better than it was without Gan. I didn’t know about fuel consumption because it doesn’t matter for me.

Versand war Top. (Paket kam am nächsten Tag) Die Installation dauerte maximal 10 Minuten. (Ich habe die Anleitung länger gelesen) Nach 500 km merkte ich, dass Das Auto schneller geworden ist. Zumindest der Kraftstoffverbrauch hat sich nicht erhöht. Soweit zufrieden. Ich hoffe, dass alles so weiter geht.

Type of product: GAN GA/GA+.
Car: Chevrolet Cruze 1.6, 124 ps
Advantages:
Ich habe sehr lange gedacht ob ich wirklich GÄN GA brauche. Zu meiner Freude gab es einen Ausverkauf und ich habe bestellt. Die Installation und Aktivierung war kein Problem. Nach 120 - 140 km begann ich zu spüren, wie mein Auto seinen Charakter verändert. Jetzt beträgt die Laufleistung (mit dem Gerät) mehr als 1000 km. Die Reaktion auf Gas ist spürbar besser, das Automatikgetriebe begann ganz anders zu funktionieren, Rucke fehlen. Der Effekt übertraf die Erwartungen. Gleichzeitig stieg der Kraftstoffverbrauch nicht nur nicht an, sondern sank sogar leicht, im Durchschnitt von 10,7 auf 10,5.
Disadvantages:
Na ja, kann man negativ sagen, dass der Diagnosestecker ständig besetzt ist – das ist nicht toll… aber das ist in Ordnung.

Car: Skoda Superb V6

Type of product: GAN GA/GA+.
Car: BMW 3 Series E46 330i, 231 p.s
Advantages:
with Dynamic mode there are really better acceleration respond, convenient mobile App, easy installation. It’s good that you can use the same unit on other cars with the same engine type
Disadvantages:
Eco mode is doubtful, according to the fuel consumption the fuel economy is less than 5%, and not up to 15% as stated on the website. When calibrating using mobile app, the progress bar does not work correctly. For example, it reaches 48%, then rolls back to 41%, and such rollbacks continue while calibration is in progress. It is annoying.

Advantages:
To be honest at the moment everything. Hopefully gets better and better.
Disadvantages:
The fact that it needs to stay in the obd slot at all times. Also it’s not clear whether it always needs to be connected to a phone via Bluetooth that has a internet connection

In my opinion well worth the money compared to the competition

Type of product: GAN GA/GA+.
Car: Subaru Impreza (II) 2000-07 2.0i (160HP)
Advantages:
- easy installation, and a very easy control app (gan app) - fast shipping and very good presentation of the product - about a +10hp -due to being an atmospheric car, increasing the hp is difficult, so at last +10hp is a great option - the hp gain is greater at high rpm and velocity - combining with a cold air intake, the hp winning is greater - cheaper than a ecu reflash
Disadvantages:
- they say that you won +19hp.... is more like +10hp - expensive for only +10hp - not very noticeable in low rpm and velocity
Comment:
in conclusion, is a good idea for gaining an extra hp for this atmospheric model, combining with a good intake and exhaust you can reach 190 hp, its true that its an expensive item for the little hp gaining, but knowing that an atmospheric motor is difficult to increase the hp, is a good option to give it an extra push to the hp

Type of product: GAN GA/GA+.
Car: GW35695
Advantages:
More power in low revolutions per minute. More relaxed driving as no need to change gears often. Mobile app control. Easy to set up. Can be set up while driving.
Disadvantages:
Looses all settings after engine turned off. Had to pair with mobile and setup every time engine started. Setup is slow. No power for takeovers (high revs for min). Reset button not working. Poor diagnostic on mobile app (missing info is engine started , is chip awake etc.)
Comments of GAN Tuning Buro:
Dear customer, The GA/GA+ doesn't lose all settings after the engine turns off. - Select your car in the GÄN app. The necessary settings will then be sent to the device. - Wait until calibration is finished (this takes 3 minutes). - Сhoose the mode (for example, DYNAMIC). - Done. After that the GA+ will work autonomously. You don't need to pair with mobile and setup every time the engine starts. You need to use your smartphone only when you want to change the operating mode (for example, from DYNAMIC to ECO).

Type of product: GAN GA/GA+.
Car: Ford Fiesta
Advantages:
Die Leistung die mein 60 PS Fiesta durch die Klimaanlage verliert, wird gut kompensiert. Man merkt ebenfalls das er etwas spritziger unterwegs ist. An sich das was ich gewollt habe und bekommen habe. Da kann ich nichts negatives berichten.
Disadvantages:
Ich hätte mir nicht den ga+ kaufen brauchen, da die App sich nicht mit dem ga+ verbindet. Dieses wird im App Store auch von anderen Nutzern bemängelt. Ich habe mir 4 verschiedenen Smartphones mit von 2 Marken verschiedenen alters getestet. Keines hat die Verbindung in der App aufgebaut, jedoch wurde das ga+im Menü das Smartphones als Bluetooth Gerät angezeigt.
Comment:
Wäre das verbinden wie beworben mit dem Smartphone möglich, würde ich es noch einmal kaufen und weiter empfehlen. Doch durch diesen gravierenden Mangel nicht.Ich würde dann die günstigere Variante Ga kaufen. Gruß Martin Seegers
