If you switch to a smaller than stock SC pulley you won't have enough adjustment with the stock idler so you need to go to a 64mm idler pulley to take up the slack (Gates #36225).

Hey, I'm sorry to bring this back and for missing this info earlier, but if I drop down to the smaller 9lb serp-side pulley, do I need get a larger idler pulley than the one that came with your kit? I'm having boost issues and everything trends correctly until top end, where I think I'm getting belt slip, but I can't hear it. I had no belt slip and expected boost with the 8lb pulley, but I'm now losing boost top end after switching to the 9lb pulley. I didn't change anything else other than replacing the serp-side pulley with the smaller one. Is this where I messed up? Thanks!

Who installed it? Very first thing you should do is go make sure the key is in there. I can totally see it having enough friction to grab until a certain point then without a key it lets go and free spins the pulley.

With the T batt mod there should be zero slip. I have sold many SC kits that does not include that mod and they do not have slip. They use my personal anti-slip pulley mod but it is no where near as aggressive as the one you have.
