Default N54 HELP, can not solve this problem? - 11-29-2021, 05:05 AM

I have a n54 135i fbo, jb4, MHD back end flash.

The car runs great when just normal driving. When applying 100% throttle there is almost no power coming in and a few seconds into the run the jb4 switches the map from map 2, to map 4.

I today replaced the coil packs and spark plugs using delphi and ngk 1 step colder plugs.
I also removed the vanos solenoids to give them a cleaning.
This did nothing to solve the issue. I took the car for a test drive and it did the same thing while I was logging, no power and a switch to map 4.
I am almost out of ideas as to what it can be and need someone who is better at reading logs than I am to help.https://nox.tips/ https://xender.vip/
