New to the army! As you can see from my name I drive a duramax. I used to follow around on the nation a little bit and figured this looked like a dam good forum to sign up with. Im here to learn a few things also, Im known to occasionaly help a buddy (STROKER) work on his truck I also saw a good thread about tuning on here from Matt@gearhead and figured I would follow it I do EFI live tuning and new info is always helpful!
