UPDATE: Swapped another wastegate on and still only 13.5 psi and way off on load targets. In an attempt to check if my cat was clogged I pulled the AUX 02 plug in my cobb downpipe and went for a drive. Boost went to 14.5psi max. Not sure if that indicates a clogged cat or not.
Afrs are spot on with logs prior to issue. I have tested the wg with the bottom port just open but never put boost to the top port. I assume that would ensure the wg stayed closed and it "should" overboost way above targets. I might try that but it won't be today. I don't feel like jacking my...
We have increased wgdc to 60 ish through that map and my boost might increase 2-3 Psi. It's ewg and I have tested it on and off the car to make sure it opens and closes with air.
One thought I've had is maybe the ECU isn't sending the signal to the ebcs to close the wastegate and I'm basically...
I working on lining up a wastegate to swap on for a day. Maybe in a week or two I'll test that. As for the maf sensor, I have checked all the wiring etc and the sensor it's self. Haven't tried swapping one out yet though.

Little update. Swapped map sensor and did compression test. 180 across all cylinders and no change with map sensor.
