This is common on Mhd n55e flashes. They abandoned the platform to work on the n55 ewgs. Theres nothing wrong with your car its the tune. I went custom tune just for this reason.

You cant log intake (after throttle valve) with mhd .. You can with Protools. The pressure you are seeing is before throttle body and once the throttle closes you would see a increase in pressure before (which you see) and a decrease in psi after throttle .. Its only like a decrease of 1 to 2 psi though.

Its really just bad maps .. Its been documented many times. Any n55e mhd map log you will see the throttle closure then excess boost.
