I have a 98 CSVT. I used to have a superchip, but at a recent dyno run I saw that I lost 5 hp in the top end. The guy running the dyno said this is common on mildly modified engines. All I have is a KKM intake and a Mass Air Meter. Maybe your setup is different enough to warrant a chip, I would spend the $250 on something else.
