we just put an ms3 in my buddys car. with the stock intake (ls1), an slp lid, stock maf, u/d pulley, kooks 1 3/4 and a 3" custom true dual over the axle setup. just to see where it was at before the fast 92/92 and the tune (im going to tune it myself) it turned out 418 at the wheels un corrected and with smoothing at 5. only revving to 6 grand!!!! i was shocked. SAE was 399.8

 

how much did he charge for the tune and do u have his number from hpe?
