I run a 93 tune on with my Diablo, find that I get the best highway mileage with the 93 tune and mds turned on. Plus the bump in performance is nice too.

I have a 2014 R/T, I am running the 87 tune with the diablo. I have ARH headers with kats, magnaflow, Volant CAI. Did the diablo last. Great improvement in power, shift firmness. Went 13.93 in the quarter with traction control on and tires still spinning.

Varys vehicle to vehicle. How much knock are you seeing? 1-2 ST knock is acceptable. Anything higher and you are losing quite a bit of power.
