I’m new here and I have some questions.

Ok, so I’ve really been paying attention yesterday and today. So here’s what I got: I did 425 miles yesterday. Loaded at 70,000 one way and empty at 28,000 back home on a windy day and averaged 4.9 mpg. Today I did pretty much the same thing with less wind and got 5.2 mpg. The manifold pressure gets to 22psi and stays there climbing the hills. On flat ground with the motor not pulling hard, engine rpm is 1500 at 70mph with 12-15 psi of boost.

If computer needs reflashed how do I even start that process? If it need reflashed shouldn’t a guy jump up the power as well? Go to 500 or even 565hp? Looking for any help I can get here. I got some more pics of my setup.
