At idle and coast down the car wants to flatline the wideband and the O2. Car has a return fuel system pressure set at 43psi and 80lb injectors from ZZP. Also no matter what I do it will misfire at WOT. Never did this on the dyno, only on the street. Car does eventually enter DFCO but not as soon as I would like. Thoughts on what is going on and how to correct the issue would be greatly appreciated.
