For part throttle closed loop, O2 sensor feedback should be well enough to compensate. Also I believe the headers will move your O2 sensor and mess with your feedback.

From my experience, and there are those that will argue, but the MAF trails the MAP. Since MAP comes first, having your VVE dialed in is beneficial for transition fueling. I for sure don't want to mess with Dynamics so I try to get the VVE as good as possible. Especially below the High-rpm enable of 4K. But that is just me. At WOT it seems to just be Fuel and Spark. Now we have to factor in Allowable TQ as well but it really all just boils down to Fuel and spark. WOT is easy.
