well i went to allens shop last friday for a sdretune with the 3.1pulley and all i can say is wow. can easily notice the difference on topend, the a/f i think it's at 11.2, and running 9#'s of boost with 18*'s of timing and with iat's at top's 110*'s WOT. compare to 13#'s of boost and 12*'s of timing with iats at 150*'splus. now time for new 1/4miles runs

 

That's better!

 

yea i think i was pushing it to much with 13lbs of boost for a 5.3l

 

Good to hear bro!!!!
