So I had a new charge pipe and intercooler installed recently and went to the MHD stage 2+ tune. I finally got on it today and went wop but when I did the car gave me a drivetrain malfunction I turn the car off and back on and it's gone.

It only seems to be occurring when I go wop. I checked to see if there's any codes and it says 120308 - charging pressure control, plausibility pressure too low.

Does anyone have an idea as to why this is happening and how I can fix it? Any and all help is appreciated!

Edit: now I'm also getting codes
102001 - air mass, plausibility: air mass too high
108F01 - intake plenum: suspicion of leaks between exhaust turbocharger and intake valves

Sounds like a leak between the CP and intercooler pipe. I had those same codes a few weeks ago and I also had zero boost, and it turned out that my coupler had completely popped off.
