A stock truck will put down from 190hp to 210hp. Remember the 250hp from the factory is at the crank, not the ground. The Superchips tuner in the 7.3 don't actually give you 110hp. You usually see about a 85hp gain from the 110hp tune. Bigger than stock tires will also make less power to the ground. Now for the good news, your butt dyno will like the gain from the tuner, I know mine did when I ran the superchips tuner. My butt dyno thought I had the baddest diesel in town, man did that dyno lie to me......
