2003 7.3 sct

[jello]

Does the xcal2 do the same for a 7.3 as it does with a 6.0?
I'm not talking power wise but shifting, change tire size, get rid of speed limiter etc. Is it like a 6.0 were you get better fuel economy out of a race file or is there a good economy file? And also what kind of power would it make on a truck with exhaust and intake?

It does have full trans control. It gets rid of the speed limiter. But the 7.3 won't spin as high as a 6.0L. The higher HP stuff does give the better fuel mileage. It will usually add roughly 100hp. You might get more but then again the more miles on the truck the more wear on the hpop and injector o-rings and other stuff.
