Which Q3 engine gains most?
The 2.0 TFSI petrol turbo delivers the largest outright gains, while the 2.0 TDI excels at usable everyday torque in a vehicle of this weight.
Is a remap noticeable on a compact SUV?
Yes. The extra weight compared with a hatchback means the additional mid-range torque is clearly felt, particularly when loaded.
Does it affect the quattro system?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
