Thread: Time to start thinking about a tune. Help

If you already have a peak of 2.1 with headers (not sure if you installed them yet) a 3.4 will double that number.

A tune might not take that away, just so you know. But I guess you'll have to see if it goes away when you install them, if you havent yet.

Considering the OP says he ordered them yesterday, I'd say they are not installed yet... haha.

Headers may or may not allow that much of a pulley drop as others have said, just make sure you scan with it after the header install.
