My first one I was concerned, then I bought a new run-in for the GLC. Paolo tuned it and "SWEET BABY JESUS" that thing was fast. Neither of them had much of a pinch but they ripped. I'm only about 90% of where lil-bump is, I want to learn how to do this on my own but it really is nice to know all you have to do is put a clutch on, tune, and you're ready to race.
