For a while i had a hole in my JIC exhaust and never new it. My car ran fine, held boost and all but when i had the hole fixed it seemed like the car didnt hold boost at WOT.

My engine mods are the following:

UTEC
Perrin Up-pipe
Perrin Catless Downpipe
JIC Bullet Exhaust
GFB Pulleys
Turbo XS Intake w/ Samco Intake pipe kit
HKS SSQ BOV
Lineage Grouding Kit

I haven't changed the seeintg on the ABC or the maps on the UTEC at all, I did notice a kind of wierd hissing sound comming from the front right of the car, not at WOT just when my foot is resting on the gas.

Any help you guys could offer would be greatly appreciated
Thanks, Bill
