Does anybody know if there is any way to turn off the rear O2's for a off road x pipe. A friend of mine had the 750HP FRPP super pack and wants to add a off road x pipe. Any help would be great.
I don't think you can with a pro-cal. I have the pro-cal tune for the TVS and there is no provision in the pro-cal to turn off the sensors. Gotta remember that the pro-cal is from Ford and they can't turn off those sensors for emissions reasons.
