that's off the shelf because your truck wasn't on a dyno with all the mods done and hooked into their a/f monitoring while the tune was completed (takes hours).

I'm not saying it's bad, but it's not the greatest tune. It's safe to drive. A real dyno tune from a good tuner like JL would be a better way to spend money than a set of gears.

The best bet really would probably be tires. I had decent tires on my truck but after I did most of my mods I couldn't use full throttle until part way through 2nd gear (over 45-50mph). It was fun doing rolling burnouts at 30mph but it wasn't fast at all...
