This is the latest shape Audi A8, the D4 with the 3.0 250 bhp turbo diesel engine. When we dyno tested the car as standard, the power was almost perfect making 253 bhp and 558 nm of torque. Due to the size of the car, the owner opted for our CustomPro remap to improve power and torque as well as fuel economy and drivability.
As you can see on the graph below, peak power is now made much earlier where peak power was made at 4,500 rpm before, the vehicle now produces the same amount of power at 2,800 rpm! The same applies for the delivery of torque, with peak torque being made quite late in the rev range at 2,700 rpm. After our CustomPro calibration, the vehicle now produces the same amount of torque at 1,750 rpm, so a massive improvement all round.
Power gained: 39 bhp
Torque gained: 96 nm
