I don't have an Allen tune but the tune I have is also good and the only mod I could notice....and a big one at that. Nelson does great work and I've messed with several trucks here with his tunes and they all love 'em. By far the best bang for the buck (especially for DBW folks) and I can tell by others' tunes he does A+ stuff. Support is awesome too 'cause of this site.
I had the predator handheld it missed up my computer had to buy a new one. Got a nelson tune very good very helpful with any questions you have worth every penny customer service is good just with that its worth it.
