Ok, so i plugged the maf back in and have been messing with it. it still kinda hunts for idle, but not as bad or as long when warm. Well I did a few WOT bursts and I did add timing a few days ago (no log though). After looking at what my PE was commanding and what the actual was, i was leaner all over. does that mean Ive got more in her? Also, if its .3 or .4x off from the commanded (higher) how do i compensate? How do I get the figures i need to put into my pe table to offset the difference?

if everything was dialed in tight while in SD, you need to make the adjustments to the MAF calibration. MAF cal is the same concept at VE calibration

let me see if i got this right. the maf takes the cmded AFR for PE into consideration when logging maf afr error?

If you'd like some more info on MAF tuning, take a read of this thread:

The MAF reports a frequency that is looked up in a mass airflow table. If PE commands 12.8:1, the PCM will look up the respective airflow rate (as reported by MAF Hz) and calculate the injector pulse.

If the MAF table has too little flow, the WB will read lean, too much and the WB will read rich.

Your error factor is simply (actual AFR)/(commanded AFR). You use the result to adjust the air flow table(s).
