    I fixed the idle problem. im waiting on my spark plugs to get here to see if they help any. but everyone seems to think i have a boost leak but if i do a 4th gear pull it boost about 5lbs BUT......if i let OFF the throttle just a lil bit NOT all the way and floor it again the boost shoots right up to 22lbs (where it makes me:)). Would that be a boost leak or something else?

    I am not mechanically inclined, but it sounds like a Drive By Wire issue of some sort. I can't think of anything that would explain getting 5 lbs of boost at full throttle, and getting your full 22 lbs at 95% throttle.

    its 5psi when i first get on the throttle. i can let off the throttle a lil bit then full throttle again and it shoots up to 22psi.its like it has to clear something out.

    aftermarket headers? Maybe a leak there and the heat generated from the first pull gives a temp seal? dunno pressure test the bish

    Do you have a boost line with a pill in it that controls the wastegate mechanically? Maybe it's getting stuck. Can you hear the boost venting out of the wastegate when you are hitting the wall at 5 psi?

    It has gotta to be a wastegate/boost controller issue.

    How did you fix the idle problem? What was wrong with it?

    i cant hear much because i have a cutout on my car. its so stinking loud. i think that my hks bov was leaking a little. i put some hi temp silicone on it and since then my car hasnt died and is idling fine.
