REVIEWS ON TUNING MODULES
GAN GA +, GAN GTL, GAN GT

When visiting the service, one employee saw my device and was not very happy with it. He made me afraid that I could lose the factory warranty.

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

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.

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) .

It is not very convenient that the Obd II plug is occupied

Very fast delivery, excellent customer service, smooth and quick processing. The module works perfectly and, thanks to the excellent user manual, is easy to understand. Installation was very quick and easy. The performance increase was immediately noticeable. I would gladly order from GAN again anytime.
