I would like to raise the boost from 22psi to 35psi by a granger valve . My question is can i do this without setting an over boost codes ?

I currently have a Banks six gun on it ,larger lift pump, and a K&N
From what i read is 1psi = 10HP on this motor.

That's a big jump in boost. I can honestly say just about every Dodge Ram I've ever checked codes on had the overboost code in it. Most of the trucks had no modifications.

It's not a serious code, it doesn't turn on the CEL. It just gets stored and does nothing. Beware, these diesels can run lean and hot and burn just as fast as any gasoline engine.
