Maf Tuning help wanted
Can someone please explain to me why I can?t get the maf to tune properly, I?ve set up the tune to maf only with DTCO off and COT off Dynamic airflow off and p0103,p0102,p0103 to MIL on 1st error. I was previously using LTFT?s only for the correction then taking the data then copy then paste special multiply % half then the next log it will be lean then the next will be rich then the next lean so then I disabled the LTFT?s and now running off STFT?s only getting the same results

Tuner in Training
Cant open your tune right now, but looks like your setup for Maf only is incorrect. Start by changing the P0 mil's back to stock. You make those changes when you are trying to fail the MAF and go SD to tune VE. Think you got the directions mixed up between modes. After that i would verify you made the correct changes to disable dynamic.

Setting these DTCs to MIL on first error should only be done when failing the MAF and tuning VE. When tuning either MAF or VE your engine temp should raise to normal operating conditions. Make sure your not entering PE mod as well. Use a wideband.
