Save your money and get a custom tune.

Contact JustinSS at Blackbear Performance - He's tuned several members trucks with results that will blow anything the Hypertech can do out of the water.

I ran a few HPP3s, didn't notice a damned thing power wise. It was only useful for speedo correction.

Spend it on a custom flash or something
