I ran tow tune all the time.

 

My dad has a superchip for his 98 ram. I used it before I got my SCT. I always just left it on the 87 tune but I really didn't notice much of a difference over stock. Even on the 91 tune. I was running 33s with 3.55 gears so that may have something to do with it.

 

i had superchips, then i went to hemifever and sct walks circles areound the superchips.
