I have a 2013 f150 v8 5.0 with a leveling kit. I live in south louisiana and I just disconected or rather deleted the muffler and resonator on my exaust system. I still have the 4 stock cats on. I am wondering if there will be any problems if i do not tune my truck to this setup because my buddy told me that since there will be more airflow that the O2 sensors will get confused. Does anyone have any comment, suggestions or answers to what i am dealing with???
