Which engine gains most?
The 2.0T turbocharged, by a clear margin. The naturally aspirated 2.4i and 3.0i gain considerably less.
Is it related to Opel models?
It shares group platforms and part of its engine range. Our experience with those units applies here.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
