What makes the Audi A4 B7 special
Audi A4 B7 tuning: engines shared with the rest of the group
The 2.0 TFSI with 200 hp was the first TFSI in an A4, and in the B7 (Typ 8E) the GAN GT takes it to 254 hp. Audi A4 B7 tuning applies to the saloon, the Avant and the cabriolet alike, because the engine decides which tuning box fits. The 2.0 TFSI with 170 hp reaches 218 hp, and the 3.0 TDI with 232 hp reaches 262 hp.
Audi A4 B7 chip tuning of the 2.7 TDI with 179 hp gives 230 hp. The 2.0 TDI PD with 170 hp does not appear separately in the A4 B7 catalogue: you will find the same engine under the VW Passat B6 as the 2.0 TDI PD 170 hp.
Where the GAN GA+ fits
The 2.0 TDI PD with 140 hp is a pump-injector engine and works with the GAN GA+. The 1.9 TDI with 116 hp reaches 130 hp. The 1.8 T with 163 hp is a turbocharged engine with multipoint injection, and with the GAN GA+ it reaches 183 hp.
Audi A4 B7 chip tuning: questions
Chiptuning an A4 B7 2.0 TDI PD: how much power does the GAN GA+ add?
The GAN GA+ takes the 2.0 TDI PD from 140 hp and 320 Nm to 157 hp and 358 Nm. The GAN GA+ is rated at up to 12% more power.
Audi A4 B7 1.8T: what does the GAN GA+ add to the 163 hp?
The 1.8 T goes from 163 hp and 225 Nm to 183 hp and 252 Nm. These are the stated gains for this engine type, not a dyno reading of your car.
Audi A4 B7: tuning box or ECU remap?
An ECU remap rewrites the control unit; the GAN tuning box plugs into the existing connectors, adjusts the sensor signals and leaves the factory software alone. Your manufacturer's warranty is preserved: the ECU software is never changed, and the module can be removed at any time.
Is a tuning module the same as a Stage 1 tune?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
