    I think you need a Jet Programmer to fix your shifting issues, seeing as how you already have a Jet module on the truck. I would bet your friend would fix that problem for you, it is not that hard to adjust the shift points.

    I'll adjust your shift points for a set of PIAA 520 series lights, and that is my final offer friend!

    $300? forget that.

    Does it shift that early even when you are really on the stupid pedal? Or just when you are driving normally? Or both?
