Not sure about a 2002 model. My 06 with the 325/610 motor can get up past 30psi.

He has a mechanical wastegate actuator. Check out Banks, BD, etc. They have upgraded wastegate actuators that allow you to build the boost higher before releasing.

it sounds like your boost is being capped... I can hit 40~45 no problem with my mods. 40 is pushing it on a stock turbo... needless to say it doesnt see 40 much.

mine would build to about 25psi when loaded, about 21 when unloaded. with the wastegate mod it'll do about 37 psi.

From what I understand, 22-24 peak is normal for '02
