Ok i just installed my mail order overkill pcm yesterday drove it for a few while not beating on it, then i did a few WOT runs and it was fine, ran great, I take it for a ride this afternoon and it runs fine soo i put it in performance mode and i do a few WOT runs and everythings fine, then going up a street normally and this is what i hear. There is no SES light on and it seems to shift fine i guess. If it would help more i will take another vid of it driving. I think it may be the supercharger, i did change the s/c oil last night, i put in 2 bottles in.
