I programmed my 5.7 with the tow- 91 octane of the supperchip. Is it possible to hook it back just to change one seting without having to go threw the entire procedure? I.E. , as to change the tire size alone , or to change the rev limit to another level?

 

well it will ask you if you want to change all those things again but just set it to where you have it and change what you want and you'll be on your way.

 

You don't need to go through returning to stock, then making changes, then reprogramming. Plug in, it will read your truck, put up the option menu, you make your changes, then it goes through the two stages of programming and spedo set, unplug

 

thanks for the info guys.
