I have had no issues with my set up, and it has a nice power boost.
4" MBRP exhaust with straight through muffler, no CAT, no resonator.
Hypertech programmer set on stage 2 (middle).
The Diablosport Predator tuner I also have (picked up used out of the local classifieds for $60) gives WAY more power, but the truck runs much smoother on the Hypertech.
As a side note, gauges give high marks in the LCF (look cool factor), but are $$ and not required. You can add a $169 Scangauge2 and monitor trans temp digitally - among other things.
The Hypertech tuning is safe - no EGT gauge required. It is the only tuner I would run without monitoring EGT. I know the Smarty Jr is also advertised as EGT "safe" - and that could be, I just don't have any direct experience with it.
Whatever you choose - keep us updated!
Oh, BTW, Diesel Power magazine did dyno tests with the stock cold air intake and several afetrmarket ones. None made any more than 1 or 2 hp over stock on a stock truck.
