Well I got around to it and went to the GM service part of the dealer I work at and got the GM scan tool and took Char around the block and whadda ya know, KR. Its fine untill I get to around 8 lbs of boost then it hits 4 and counts down to 1 as the engine speeds up.
So I'll have to stay off the boost for a while untill I can either get a 3.5 pulley or get a hi-flo cat put on.
With the cat I cant be POSITIVE that that will get rid of KR and the warrantee might not like me doing that either so its sketchy on whether or not to go for that.
