I just purchased a used SCT tuner which is supposed to have a 91 octane, 93 octane, and a race gas tune. I also have an under drive pulley coming. Truck currently has a k&n cai.
I will be installing the 91 octane tune when it arrives as that's my only fuel option where I'm located. Question is, will I need a special tune just for those mods?
Thanks
