K guys I have been working on this for a couple months and still cant figure out how some of your trucks did it. The ones that worked did you kust put your sensors back in, do you unplug them. Did you mount them on the outside. Have you had the rev b flash. I am going to get mine reflashed again to clear the codes. And try something new. I was thinking if you unplugged all the sensors, you would still throw codes for the sensors not working but you wont throw the codes for the cat being full and such so it shouldnt detune the computer.

Please only answer if you have straight piped your 6.7.
