    You won't get much support for rolling coal. Deeply frowned upon in the tuning community. Clean tuning with maximum power is where its at.

    I can help make solid power out of your truck but you have to also understand dumping tons of smoke vs making a lot more power cleaner is a night and day difference. Do you have any modifications done to your LB7? Do you have any transmission updates? There is a fine line also with wanting to drive the truck like a bat out of hell and driving normal with some hits here and there. Do you do any pulling with the truck or is it just a daily vehicle, you are trying to get good fuel milage with and turn it up to not feel like a slug i its stock form? I will say this even a conservative calibration really wakes up the LB7 they are extremely detuned from the factory most likely to get the longest life out of the transmission due to its inherent weakness with oiling.
