I know that they have software so that you can connect a laptop computer to the dianostic port, and change rev limiter, the way is shifts, and stuff like that, but I can't find it anywhere. does anyone know where I can find this at?

 

I would not recommend going that route unless you REALLY know what you are doing. If you forget to make a backup before you make these changes, you will put yourself into alot of trouble. A hardware programmer tool is the best way to go and the safest way to go.

Examples are;

Hypertech III

Superchips

These are programmers, not piggyback chips. They will backup your stock settings, then you can change whatever settings you like and enjoy. If you need to go back to dealer for work, you can revert your PCM back to stock.
