Frequently asked questions

• Is an ECU remap required? Yes. A suitable ECU map (Stage 2) is essential to get the full 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 high-flow catalytic converter: it keeps real emissions control while flowing much more than the original. It is the choice of tuners who want to keep their vehicle clean.

Why choose Milltek Sport?
