So, the car is a 2021 Mach 1 with 12K, an ESS G3, Stainless works long tubes, hi flow cats and H-pipe.
Original tune wouldn't allow the car to complete readiensss sequence.
New tune get through readiness, but was throwing the typical p0420 code so I installed some mini-cats (non-foulers) on the o2s by the cats. p0420 errors gone.
However....now the car is throwing a p0153 and p0133 errors (slow to respond of the drivers side front and passenger rear o2s) and getting some stumbling while driving.
I'm not one to automatically start blaming the tuner, so I want feedback IF there is anything that can be adjusted in the tune to lengthen the time allowed for the 02s to respond. Or do I need to be looking somewhere else?
This is hanging me up on getting emissions test completed and getting a tag on this thing, so any constructive feedback is GREATLY appreciated.
