Questions on ECU tune, Secondary cat delete, and will a dealer remove top-speed linit
- would the dealer be able to detect if a piggyback product was used, if its removed before bringing in to the dealer for service?
- does anybody use this product and have feedback?
- can the face-lift, 2019+, C63s AMG coupe handle that kind of power increase without modifying other stock internal components in order to support the power increase?
