KrisJulia Cruz Posted October 11, 2015 Posted October 11, 2015 I have a 06 sierra 1500 4x4, it has a 7" fabtech lift I just put 35" tires and want to adjust my shifting points accordingly I have a super chip for it so I can program it. But I can't find anywhere what my shifting points should be. Where can I find this info?
