I noticed an issue with my 07 Sport that when I was accelerating with my foot to the floor it actually accelerated much harder when I lifted an inch or so. Is this a TPS issue?

 

wide open throttle cuts timing back and adds too much fuel

WOT really only works best for carberated motors these days, the programming always thinks it needs extra reliability over power when the throttle is maxed out.

My car is the same (2013)
