Anybody running the Trinity on a 2008-2010 Hummer H2 6.2?
I have one on my 08. Great product, truck is much quicker, smoother acceleration & gas mileage is a bit better and that is with the 93 Diablo tune. I am running 38's, the programmer will adjust everything for the size tire you have, so the odometer is correct now. It is very easy to use, update, download & install tunes. All kinds of gauges and features. Cant say enough, but if you want more, like most people do
Look into the Diablew Tune; it is worth every penny, plus++++. The Truck runs incredible now, ten times better than with the 93 octane tune, and that is a good tune. Lew is the greatest, very nice and complete, can’t say enough about him. A+++ guy. I didn’t care too much about gas mileage, wanted to work on the acceleration, but gas mileage is now back to stock, with running 38's. It get just about the same gas mileage as every other Full size SUV or full size American truck out there, soooo tired of people complaining about H2's and gas mileage. Oh well... 
If I wanted 50mpg I would of bought a hybrid, but I don’t.Just my opinion, but the Trinity is an excellent buy.
Thanks
