Frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 map is essential to get the gain and avoid a check engine light related to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• 200-cell sport cat: it keeps real emissions control while allowing much more flow than stock. It is the choice of tuners who want to keep a vehicle clean.
