P0470 after switching back to factory calibration?
Just a quick question that I'm hoping someone here can shed some light on. After I flashed the PCM back to the factory calibration (have to go through NJ
inspection), the truck started losing power and hissing through the exhaust like the cat was clogged. I put it on the scanner and came up with P0470, an exhaust back pressure sensor fault code. I know that this is a common code when running an aftermarket tuner, but I'm kinda stumped by the fact that it only appeared AFTER I went back to stock. Any thoughts on the subject?

That's my thought.
