Random Limp mode when going over 4000 rpm

[kendrickmorales]

Hi everyone!

Currently helping a friend out with his car that seems to lose power whenever he hits a pull at around 4000 rpm and the car seams to go into limp mode and run poorly and it give out the p1010 MAF code every time. He changed the MAF twice now and still keep having issues. Do the readings coming from the MAF and MAP look normal? I'm fairly new to this so any help will be appreciated


I included the tune file and couple log files as well

You need to pull codes after it goes into limp mode. P101 is a code but will not cause limp mode. I don't think P1010 is a code

Sorry, I meant p0101

I didn't see anywhere in the "pull example" log where it looked like it went into REP. It is a cable throttle body engine so it shouldn't be able to go into limp mode. In the data log there's a pull to 6000 RPM.

The narrowband O2s are disconnected so you can't see what the fueling looks like. No telling how rich or lean it is.
