I really purchased this tuner so I could purchase/upload a custom tune for my 2010 Camaro after I install my long tube Kooks headers with hi-flow cats. In the interim, I hooked it up and adjusted some parameters (axle ratio, idle RPM ) and uploaded SCT's tune. Seems straight forward. I'm not sure I can feel a seat-of-the-pants difference. I did notice the tuner already has a tune on it for long tube headers! I will upload that tune and evaluate before purchasing a custom tune.

Huge difference from stock. Except that the instructions are not too clear, this tuner/programmer is an excellent device for the spirited driver who don't mine using high test gasoline ?. My 6.2L truck became really fast and drivable.
