If your STFT and LTFT are off by ~5% or more you'll probably want to rescale the MAF to get that closer to perfect. If you want to look at that, you'll need to log AFR, AFR commanded, MAF voltage, IAT and fuel system status.

If the MAF scale is off, whatever AFR your tune is commanding won't be what is actually coming out until the trims stabilize, which for WOT will take a while.
