Any info on what tune you are using with this?

Diablo has a tuner.
RPM Extreme sells a custom computer you swap out (ran this for some time and was very happy with it).

I am guessing you dislike the diablo. Right after I post this I am going to put up my experience with it this past weekend (not good).

I ran their ECU up until I got the tuner. I saw improved gas mileage and power. While I do not have a dyno report, it was noticable. My in town mileage went down. My highway mileage went up. Power band started lower in the rpm range (1500 or so).
