Recalibrated MAF after fuel pump... WOT AFRs rich

So my LTFT's were off a bit since I got my PTP fuel pump, but I couldn't do anything about it, because my AP was in the shop at Cobb. Well, I got it back and today I went to recalibrate my MAF. I only put about 5 miles on the map before I pulled one WOT run.

The good news is that my LTFT's are practically nil... The MAF g/s log I did and subsequent adjustment got my LTFT's within 1% :D. However, my WOT run was definitely rich, even post shift, when it is typically a little leaner. I'm not sure if the car has just not settled into the map yet for WOT runs or what. I'm only going to be using this map for the next week or so, until I can get at a garage to install my CPE FMIC, and then I'll be on to the Stage 2 TIHSF + FMIC map. Let me know what you think.

Thanks,

Doug

PS. I was checking my LTFT's first, so I had 3 tabs of my fuel trims, and then added the WOT log tab to it.
