MAF sensor mode, Speed Density, and AlphaN can all be open or closed loop. With a Pure Stocker, I would certainly leave the MAF on it. I don't think it would be legal to remove it, would it. At least the original Pure Stock rules would not allow it. This new "pure stock " ain't really purely stock. May be legal now? I don't know.
Anyway, if you know how, you can stop long term fuel trims from effecting WOT fueling.

Do you guys run open headers? You most certainly don't want closed loop, with a factory computer, with open headers.
