Log in as a professionalFrequently asked questions
Which version gains most?
The turbocharged 3.0 DFI of current cars, clearly. Boost pressure gives far more to work with than a naturally aspirated flat-six.
Does it affect the all-wheel-drive system?
No. The work is done on the engine ECU and does not alter the operation of the drivetrain.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a car in this segment.
