Not sure which engine you have?
The badge alone is not enough: in this generation, the same engine designation came in different power outputs, each with its own calibration. Check the power output in your registration document and find the matching row.

Audi A6 C8 tuning: what changes
The tuning module sits between the sensors and the engine control unit (ECU) and adjusts their signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

What makes the Audi A6 C8 special
Audi A6 C8 tuning: the numbers on the badge are not litres
On the Audi A6 C8 (Typ 4A) the badge number is a power class, not the engine size. Reading it right is the first step in A6 C8 tuning with a tuning box. A 40 TDI is a 2.0 with 204 hp, a 45 TDI is a 3.0 V6 with 231 hp, and a 50 TDI is a 3.0 V6 with 286 hp. From 2020 the 45 TDI has 245 hp. The 245 hp 45 TDI is not in the catalogue.
A 45 TFSI is a 2.0 that had 245 hp until 2020 and 265 hp after it. The 265 hp 45 TFSI is not listed separately for the A6 C8; the same engine appears as the 45 TFSI 265 hp of the facelifted Audi A4 B9. A 55 TFSI is a 3.0 V6 with 340 hp and a single twin-scroll turbocharger. The 55 TFSI e is a plug-in hybrid whose 367 hp is the combined output of a 2.0 TFSI and an electric motor.
Petrol engines and what to check first
On petrol, Audi A6 chip tuning with a GAN GT takes the 45 TFSI from 245 hp to 287 hp and the 55 TFSI from 340 hp to 398 hp. High-mileage Audi A6 C8 diesels need a check first: injector and dual-mass flywheel faults are possible, and a damaged chain drive on the V6 TDI is especially costly. So check the service history and run a diagnosis before you add power.

Audi A6 C8 chip tuning: questions
Audi A6 C8 chiptuning: what does a GAN GT add to each diesel?
The 35 TDI with 163 hp goes to 197 hp, the 40 TDI with 204 hp goes to 247 hp and the 45 TDI with 231 hp goes to 270 hp. The 50 TDI with 286 hp goes to 335 hp. These are the stated gains for these engine types, not dyno readings of your car.
A6 C8 55 TFSI e: which engine figure does the module work with?
The 367 hp is the system output of a 2.0 TFSI and an electric motor. With the GAN GT it goes from 367 hp to 429 hp of system output.
Audi A6 C8: tuning box or ECU remap?
A remap changes the factory software of the ECU. A GAN tuning box does not, because it only adjusts the sensor signals and the flash counter stays untouched. 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.
