What PSI are you guys hitting on MHD Stage 2+ N55e


Apr 27, 2021
Hello, just trying to gather some data on everyones boost levels for MHD Stage 2+.

My FBO E92 N55 peaks about 14PSI then tapers down to 11PSI on MHD stage 2+ 91OCT which seems a bit low for that level tune. I have replaced plugs,valvecover,boost solenoid, checked all vacuum lines and boost but still struggling to make more than that. I have been chasing low boost for months now and Its either 14PSi is normal or my turbo is on its way out at this point.

WGDC remains below 70% and target is usually 15-16PSI
