How much does the 3.8 twin-turbo take?
It is a twin-turbocharged flat-six with genuine headroom, even from a very high factory output. Stage 1 works with standard hardware.
Why is Stage 2 dominant here?
These cars are used on track and almost always arrive with exhaust hardware already fitted. Stage 2 is what takes advantage of it.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
