Hey guys, I was hopeing you could shine some light on this, heres the facts about my car:
-My car sat for a good while before I bought it
-No boost at all, under any RPM.... I cant go past about 4500rpm, it just boggs
-back firing like crazy
-I did the vaccume hose job, and every hose was good, I even replaced 2 seliniods
-the boost gauge i have will show negative pressure, but will never go above -1 or 0
-boost gauge is plugged in to the proper nipple on the UIM

Thanks,
Jeff
