So I am having this weird issue that I can't figure out.
Done boost leak, DP seals, turbo seals etc etc etc I even changed the vacuum pump.
My boost drops drastically once I hit the pedal until 5K~ RPM I tried everything possible nothing seems to work except when I modulate the boost solenoid via JB4 & my wastegate based on JB log is at 50 which eliminate the boost leak or vacuum leak.
I can keep running it with JB4 and call it a day but I prefer to log all the parameters provided by BM3 or MHD.
Without JB4 modulation

With JB4 modulation

Any guess is welcome.
