Hello All,
I am new to owning a GP and need some help. I have a base GP with just a plain 3800 ser 3 motor. i already did the tint and the went visors and planning mods for the body. where i need the help is the powertrain. i have done the cat back exhaust and the K&N cone already. Is there any place where I get a reflasher program for my 07 GP? I have contacted a few i know of like hypertech, OBD2, and super chips and they do not make anything for it because of it being so new. I am looking to tweek it a little on the shift points and maybe a little more performance. planning this summer to add controll arms from ZZperformance with some other mods from there to come. Can anyone help me with tuning my computer??
