TP changes with the MAF sensor, so when those loads are added, the engine idles up and draws more air.
My point is, how do you know when the TP being reported is NOT the column in the fuel or timing maps being used? That's when the TP reported is misleading and it happens based on TPS when the throttle is open, not closed.
