Diablo Sport T2 Ex 2012 SS
 

I was nervous about this purchase. I had never ECM tuned a car before. I have owned this 2012 SS for about 3 months. I added a CAI. One annoying thing about the car was this exhaust droning. After reading up on the L99 engine I discovered that Active Fuel Management was the cause of the sound. So I bought the Diablosport for 340 plus tax. I added a 91 high Octane tune, shut off AFM, Removed the speed limiter and hard shift tuned my six speed transmission. What a world of difference. It was easy and it basically has the gas mileage without the AFM. It feels much more responsive.

I wonder, is there a way to manually a canned to compensate for the CAI? Im still learning. Fun.
