I think I am at around 125hp that will be the difference i think.
with diesel price right now I am not sure that a 2.2 at 28 mpg would be about the same.
But not as much fun.

i have mine set up with an om617 ax_15 combo and i had to change my rear gearing from 373 to 308s to hold 70 comfortably. I have the pump max load screw cranked all the way and the alda turned out prolly a full turn also disconected the wastgate hose. mine blows plenty of black. i get around 16psi now. i was hauling a trailer with a harley behind me and i was getting about 35mpg. Ive been real happy with the truck since i completed it. just cant keep a alternator belt for more than about 1500 miles. its also not a turtle maybe a little slower than the 2.2 was but i have much difrent rear gears now.

 

I'm turning 3K at 70mph.
running 4.56 w/35s

I don't have OD, so my final is 1:1

What would you call comfortably?
