Yeah, but he's chipped with a boost enhancer. 15psi is about where the stock wastegate shows it's age.

If it feels weak at 15psi I'd be looking at your state of tune (i.e. A/F ratio). 15psi should pin you in your seat if properly tuned.


A loose IC hose clamp is enough to cause your boost problem. Running without hose clamps (don't ask why) I found the hoses opened up at ~2psi.

Is the idle problem any better?
