I got my truck tuned this afternoon with Chris White's (GTPprix) tune that he is releasing. All I can say I WOW : what a difference. Thing pulls so much harder through all gears. It also no longer falls on it's face in the 1-2 shift. I have also put about 50 miles on it since the tune and my fuel mileage has stayed the same according the the D.I.C. This is by for the best $400 mod you can do to these trucks.

The truck now is now tuned the way it should have come from the factory.

Also while I was there Chris and his tuner were doing some development work on the 2wd program on the dyno. On simulated 1/4 mile runs the truck picked up 5 tenths over the baseline stock runs.

This is a mod that you can't believe how good it is until you try it for yourself.

Chris, If we eventually go with a full exhaust including headers and high flow cats, and an induction system, will this require a custom tune?

Slvr drop me a PM or email I'll see what I can setup :)

Jonny, intake and cat back will be just fine with this cal, in fact it'll run even better obviously. If the headers in question are of the long tube variety then yes they would require an update which we can handle.

A custom tune should not be required for longtubes. LS1's and LS2's run fine on stock tune with longtubes. :m2:
