How does the supercharged 3.0 TFSI respond?
Very well. Forced induction gives it real headroom, and it is the most represented engine in our S5 catalogue.
What is the DL501?
It is the dual-clutch transmission ECU. Work on it adjusts shift points and torque limits, and often complements an engine map.
What is Stage 2 and do I need it?
Stage 2 assumes mechanical modifications such as intake, exhaust or intercooler. If your car is standard, Stage 1 applies.
