Am I leaving any power on the table?
I have heard people say that our trucks will de-fuel once the map sees 22psi.
22psi is all that I have seen on my gryphon, I think because that is as high as the map sensor will read. (so I guess I could be making more)
I also get a P0238 over boost, and P0478 exh back press.
If this is all true will a over boost relief valve cure my codes and give me full fuel? (more power)???
