Ok so in the next couple weeks im ordering a JLT intake, SCT tuner from brenspeed and an SLP catted xpipe. A couple weeks after that I will be having 4.10s installed in the car, im wondering if I should order my tuner programmed for 4.10s and wait to do everything until I throw the gears in, or can I get the tuner programmed for the intake, xpipe and just adjust the ratio in the programmer for the gears later once they are in? Im new to this whole "programmer" thing, i used to tune my old car with basically a standalone setup, not used to this handheld dealie. Thanks guys
