I finally upgraded to HP tuners so I am selling my Diablo. With this tuner, you can get custom tunes from Diablew.com and he can send you whatever you need based off your data logs. I used it on my 2016 Yukon with a cam awap and it ran pretty good but decided to go more power so I reach limitations of what he could do by email. This thing is $390 new selling for $250 shipped anywhere on the lower 48 states. Go to their web site to see all it can tune.
