To the credit of those who called you out on the weight of your truck you never mentioned any of the huge weight adders you had made(winch, wheels, etc). As for the tuning issue you are right the trinity can be a decent choice when used to load custom tunes. As for parts on your truck that you have added to better your truck....... Please go back to the list I made for you.

Welcome to the site and hope you are different than the 99% who come in with the same attitude as you are displaying. Most won't last 3 months. Also I put money on the fact that there are still a few "gm weak links" left in your truck.
