I recently bought a new 2012 gmc 2500 6 liter. I wanted the diesel but got an awesome deal for this truck and just couldn't pass it up. Anyways I'm gonna be putting 35's and a lift on it but before I do that I wanna gain a lot more hp and torque. I've already been lookin at supercharges and programmers and cold air intakes etc., but I wanna get some other opinions on what I can do to make this truck **** on wheels. Money is hardly a variable cause I've been saving for a long time to do this. Lookin forward to hearing some good advice.
