Okay. Had my Sr on the dyno today doing great. Crank up went well, as with driveability. My problem is it will not enrich under boost. I had to switch my broken apexi map sensor over for a aem 3.5 bar. My cars running 850cc, gr3071r and so on. Apexi power fc for management. Need help quick.

Could it be the auto correction overriding what I'm doing with the hand held? Can it be turned off?

I can help you more if you want to link up with me as a client, but just from this it sounds like your fuel pressure regulator is not rising rate or is not working, or your fuel pump is sht or your running out of gas and your gas gauge is shit, happens all the time actually. Usually the simplest answer is at fault. You can try turning off the 02 feedback control too as you mentioned as a test but that shouldn't be working under load, the pfc is supposed to be open loop at that point...
