How much does the 2.0 TFSI take?
It is a turbocharged petrol with real headroom, one of the most rewarding engines we work on. Stage 1 works with standard hardware.
Why is Stage 2 dominant here?
These cars often arrive with exhaust or intake hardware already fitted, and Stage 2 is what takes advantage of it.
How does it differ from the TT2 entry?
They are consecutive generations, with different engine management. Each has its own entry in our catalogue.
