airraid cai, bbk longtubes and hiflow cats, doug thorley catback exhaust, trifecta tune. The tune turned off the o2 sensor codes I was getting, but then I kept getting the misfire codes. We changed 1 of the injectors, but I was still getting misfire codes from that same cylinder and other cylinders.

I clear the codes on the EZ Flash program. The next day I go to start the car, on the cold start the car runs real rough and the CEL comes back on with the misfire codes.....I did hear that there is a service bulletin for cold start issues on the v6. What if i flashed the car back to stock tune, brought the car in to the dealer to get the updated flash for the service bulletin, do a datalog with the new flash and send it to Trifecta? Perhaps they can rewrite the tune so that it doesnt override the dealer flash?

Idk, its just frustrating because I cant pass inspection and I am overdue. I figured the tune wouldve taken care of the CEL coming back on
