Hi

I am no mechanic but could it be that you are leaking boosted air before it enters the throttle body...perhaps somewhere before or after the intercooler at a hose clamp joint? Or even the intercooler itself?

regardss,

Richard

Purely wild guess but this happens a lot when working on an engine:

Knock sensor unplugged ?
