Car wont show boost till 30 percent throttle or above, more throttle more boost, so if your seeing 1-2 bars @ 30percent id think thats normal. If your seeing 1-2 bars 100 percent throttle at 5K rpms then you have a issue. Id suspect the BBV,Map would be the issue. It would take a Huge vacuum leak to bleed boost. If you start your car and it sounds like a Huge cam Ls1 then maybe its a vac leak issue lol

ok here is how to check it for sure. take your car out driving and floor it and see how many bars you get at WOT. if u dont have all bars open your hood and locate your boost bypass valve on the supercharger. Here is a pic
there will be two vacuum lines goin to it. one goes to from the bbv to the cap on top of the s/c like u see in the pic and the other is facing towards the front of your car. Unhook the rubber vacuum line that is facing towards the front of your car from the boost bypass valve. And then drive your car and go WOT and see if you have all your boost bars than. if you have all of them than you need a new bbv. Good Luck

Oh! Ok lol thanks! If I have any of the issues that you guys stated how much would it run me? I just got it and I like it
12-13-2010
hopefully its jsut the bbv cuz that is only 40 from zzplol or possibly cheaper on rockauto
12-13-2010
??????! What does WOT mean? Lol
12-13-2010
i had the exhaust problem u r having bcuz my boost gauge was reading that im only puttin out about 4 psi from the s/c when im suppose to be puttin out about 10 psi. and i unhooked that vacuum line from the bbv and at WOT i got what i was suppose to be gettin and a new bbv fixed it

Great you guys. You guys are awesome!
12-13-2010
no problem sir
12-13-2010
Will do

I have BOOST! I guess I wasnt flooring it enough! Thanks guys. But now I have another problem. The guy before me didn't tell me (maybe he didn't know?) but he has hid lights installed and whenever I turn them on my interior lights flicker and I felt the car lose power
12-13-2010
does it happen when u first turn them on? or does it consistantly happenw hen they r on?
and what fixed your boost problem?
12-13-2010
He probably does not have a relay harness for the HIDs. That would help big time with your problem. Relay harness is only about $10-$15..
Not too hard to hook up, we can explain.
12-13-2010
It happens consistently when they are on boost, and my foot fixed the boost problem lol. Now I know I need to hit it at WOT lol. And your guys have been extremly helpful. Where can I get a harness? And yes I would need instructions
