[QUOTE="clinton2003, post: 15996088, member: 144769"] not to be a dick, but WHY are you running a full exhaust at that boost level..... Easy way to find out is strap the H pipe to your trans brace and take off over axle pipes and mufflers. see what happens. if you can take off the H pipe and leave cat deletes on (need a bit of pipe after O2 sensor for correct readings) that would be better. see if you get more boost. I wouldnt think with the ams you would need a bigger wastegate spring.... my car, stock hellion setup, with 64's makes as much boost as i want it to. I have a cheap boost controller (Daytona TC-1) and 4 port solenoids with dual 4 port solenoids. i have 0 issues controlling my boost. After the hellion down pipe, where it would connect to the cats, i have some custom pieces made, comes down flat, to a 9" long (overall 12" long) by 3" ID resonator then a turndown. exhaust ends about mid door, and connects to the trans bolts of the transmission cross brace. Solid and quiets it down some without restriction. [/QUOTE]
