Heres the thing. Dyno numbers don't mean shit unless each truck is there the same day same conditions and operated the same way on the dyno to even compare numbers and baselines need to be set that same day. Yeah pullers don't always run down the strip but lets put it this way. Seems anymore the stock turbos are running mid 12's @ 105-108 mph. Look at the turbo you want and see what numbers it's putting down at the track. I want the best power curve not the most peak power. If you don't run the number supported by the dyno numbers but want to talk about peak power than find a Cummins guy to do that with as they make big power and most are turds. If you want or need a stock appearing turbo than your answer will be cheetha or danville. If you don't care about stock looks than get the best bang for the your buck if there is a deal out there. Most important make sure the person tunning it gets it right so someone with less mods dosen't beat you!! For the money the htt seems like the obvious choice but what do I know I run a stocker.
