How much does the 3.8 twin-turbo take?
It is a twin-turbocharged V8 with genuine headroom, even from a high factory output. Stage 1 works with standard hardware.
How does it differ from the MP4-12C?
The 650S is its successor, with more power from the factory. Each has its own entry in our catalogue.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
