I wouldn't rule out the fact that you're using a **** hack-tune with that missing link crap.

The MAP sensor can only take so much pressure, don't forget, unless you have forced induction the pressure is negative. You may simply need an aftermarket MAP sensor.

Syndacate has your answer i think. Stock maps are only rated for 10 psi, but that varies with different turbos because of cfm. Get a gm (general motors) 3 bar map for around 50 off ebay and you'll be fine.
