Car running LEAN right after it was running fine for what reason?

For whatever reason, your car is commanding that afr. I dont see anything out of whack. Look through your tune and see if you can figure out why it would be commanding such a lean afr.

Not the graphs, the AFR MAF error chart at top. Big difference. In the graph I wasn't locking in to a particular frame.

I'm doing an OL Maf tune right now. And I've noticed that I can have the MAF tuned withing 1 or 2 percent, then take it out the next day and it is off 5-8 percent.

Sheesh, why can't I edit posts? Anyways, I wanted to add that I set PE to zero across the table. Commanded afr is 14.7 across the table. This was from a guide on how tuners. But for some reason my car commands leaner afr until like 20% throttle, even though PE throttle table is zeroed out.

Is it possible to flash a stock gtp .hpt tune to my car and start from scratch? I'm still on my stock n/a tune, and I think I may have f'd up some time tuners tables years ago before I lost my dhp tuner.
