I have a 2004 Dodge Ram 2500 with the 5.7 hemi in it it’s got new plugs, wires, air filter, and a fresh oil change. I have cleaned the t.b. Twice to make sure it was spotless. I have done 2 back pressure tests on it to make sure that was good. Right at a pound. I have checked fuel pressure and that was at 50 lbs. I am running out of ideas I lose 5-10 mph going up hills even with downshifting into 4th gear. It is not throwing any codes anyone have any ideas?
