I just bought a very clean 04 Lightning with 61k on it. She is untocuhed in everyway! Dont wanna go crazy with it, I just wanna do some tasteful mods without having to have a tune! Im thinking exhaust, smaller pulley, cold air intake and a diabosport or other handheld tune! Just wondering how fast this should be be, Kinda looking for a high 12 low 13 sec outta this!!
