Default N54 HELP, can not solve this problem? - 11-19-2021, 01:30 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.
10.0.0.0.1 192.168.1.254

I have attached the log in a csv file. I never let my foot off the throttle I had the car in manual shift mode
