How much does the Polo GTI take?
The TSI engines are turbocharged with genuine headroom, which is why so many owners go beyond Stage 1.
Why so much Stage 2 work?
Because a large share of these cars arrive with intake, exhaust or intercooler modifications already fitted. If standard, Stage 1 applies.
What is the DQ200?
It is the dual-clutch transmission ECU. Work on it adjusts shift points and torque limits.
