i'm planing on getting a speedcal. my question is can i reuse it.say i change my gears back to stock or go higher ratio , can i reuse the speedcal.
maybe what i'm trying to say , is it adjustable??
I tried to read about it but they dont really make it simple http://partshopper.com/fordmustang/itemdesc.asp?CartId={01BA167C-827D-40C9-BE6D-1AEVEREST6C4DEBAD2D}&ic=DMP%2D9910&eq=&Tp=
they say i should send in my gear ratio and tire size. is that mean the will programe it and send it? can i programe it myself or something
to make it short How the F*** do i use it
thank you
