I know there's video of the supercharger kick in and cut off but mine seems really really in-consistant and I'm sure I'm not the only one mine seem's to kick in @ 2000 rpm not sure about cut off but it's usually not the same and it does not kick in consistantly @ 2k rpm it always seems to drift in and out on it's own also how do I know if my tensioner is really bad I have some slippage right now and have parts coming for my diy beltwrap should I replace my tensioner now or wait til I install the beltwrap?
