Have been running the 91 tune on my 2012 Charger SXT for the last 3 weeks. Just filled up with 94 and re-tuned to the Diablo tune, wow, what a difference! It's like a completely different car. More power and torque through all rpm ranges and the sound of the engine has taken on a "nasty" growl, even with stock muffler set up.
One question though, if I revert to stock tune, is this to be used with 87 or 89 octane? If I have a cai, is this not a "good" tune to be running at? Would I have to make some minor parameter tweaks? With the Diablo tune, I can sense the car needs a little more fuel in the mid to higher rpm ranges, should I look at and adjust afr in the WOT menus?
Thanks, and great product Diablo!!

You can still use 94 octane when you revert back to the stock tune. You just won't notice the extra power.

As far as the CAI, just add 5% more fuel at the top RPM's or WOT.

Thanks for the response. Do I have to make any spark adjustments too, what about throttle increase?

You can play with the throttle boost but I'd forget about the spark adj.'s unless you data log and know what you're doing.

thanks.

You say that you are running a CAI? i got a 2012 sxt stock except i find the 91 tune way better. maybe the cai is all the difference?
