Frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 tune is essential to make the most of the gain and avoid a check engine light caused by the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• High-flow sport cat, 200 cells: it retains real emissions control while flowing much more than the original. It is the choice of tuners who want to keep the vehicle clean.
