Truck running rich
2008 F-150 lariat 5.4L
I had gotten exhaust work done and had removed the cat and muffler and gotten true duals all the way back, since removing the cats I had gotten 02 fault codes and system running rich. which I expected. I am trying to find a way to fix the air to fuel ratio but I need help to make sure it will work. I want to get a tuner with custom tunes to have corrected air to fuel ratio, but i want to make sure that the truck wont be able to adjust the AF ratio after the tuner it programmed. Anyone been through this or able to help clarify for me?
