evo IX not boosting?
If he hit 33psi, then it wasn't running base wastegate pressure. When you get the lines backwards, it causes uncontrollable boost spikes.
My Buschur TBE will be ordered this week when I am paid for the sales of my other 2 cars. Untill then, I gutted the cat, and am running anti-foulers



Always love to hear it when I am right.
