boost issue
just had a boost issue the car peaked at 15psi hard on the throttle while my foot is on the throttle it hit 15 then dropped suddenly to like 10-11psi and held there.
maybe a boost leak? sorry for the noobie ness.. im also getting another p0100 last time the dealer said a wire came loose from the torque. on the ecm side and the sensor itself was legit. i cleaned it with maf cleaner kinda annoying.

maybe the car was compensating with a lower boost since it has the learn down feature?
does it feel slower than before? if not it probably isnt a boost leak. im pushing 27psi and all i have is the same charge pipe as you after the turbo

Maybe learn down, When I was stock, I boosted 20psi about. I ran around thinking I had GMS1 for the longest time.
Then I realized I didn't have GMS1 sensors and just learn down gave me more boost.
Also when I was tuned by ZZP and completely, I boosted like 23psi then went down to 16psi before I hit redline. I didn't have a boost leak either. It was just how I was tuned. So I went below what I was doing stock for a bit. I still dyno'd more than stock, but I boosted less.
