all though a live tune could and is probably better, and the thought you live across the country from allen nelson, i would look at it this way, how much is a dyno tune in your area? how much is a street tune in your area? is the person you gonna have it done in your area good, great or just ok? theres alot of variables, like say if you were to buyt hptuners, do you plan on getting more mods later? going to a bigger engine ( more cubes) ? theres a few things to think about, all though all does one hellva mail order tune, having the tune tweaked makes it all that better, with hptuners allen could get your tune dead on, since you'll be sharing files back and forth...BUT if you dont plan on doing much to your truck then maybe wanna think about a dyno tune or someone that has the capabilities to street tune it
