Go for it you definately got the know how and your in the right place. I read for like 2 months before I got HP tuners. Mail order tunes are alright but they can really only tune for wot
99.999% of the time your not at WOT Ive picked up alot of power and taken time off just by getting the part throttle tuning right. Go for it you wont be sorry

you're certainly smart enough to pull it off yourself. taking your time you'll get it just how you want it. if not there are many out there to help. i tune trucks on a regular basis, it's not bad once you get used to the software. i use tunercat and hptuners. if i can be of help to you at all you just let me know.

Deckhand I think a set of stage 3 5.3 heads on a 6.0 would perform well in an NA setup.
