Out pull yes, but out run I doubt it. The 6.0 has such a nice curve compared to a tuned 7.3. Yes the 7.3 might make more power peak to peak with the 6.0 being stock, but the curve is so peaky and short it will not outrun the 6.0 stock. You may get one from a roll but not both trucks from a dig just because of the variable veins in the turbo on the 6.0. I have spent many hours at SCT, Superchips, diablo, and delta force as all of them are about 15 minutes from my house and they often need donor vehicles as I have donated 5 cars for almost each of them to tune.
