So it was probably too high ACT that caused the cut back in boost. It was 19-20 degrees that day. Had no problem last weekend, the temperature was a couple degees lower but I used the air filter box, I decided to try open filter for this weekend. I'm sticking to the box from now on. Using standard IC. Had no problems two days in a row last weekend, and this weekend the open filter fucked it all up. Correction, the boost peaks at 16 PSI not, 17 psi. Holds 14,5 PSI.
