I bought a diablo Dcx for my 2012 charger rt . I registered it now I got a code what do I do with that? Wheres the 93 tune is that the diablo tune? The options are the diablo tune 91 tune and modify the stock tune.

Diablo Tune is the 93 octane tune.

Thanks some gas stations only have 91 would this hurt the car if I used the 93 tune ? I also read you post a +5 rich increase with a cai what about setting the cooling fans at?

Can't run 91 on the 93 tune. Hemis knock even if you use the right octane, using less will do damage. +5 is close for a CAI, but that depends on the intake. Some are no better than the stock box and don't need it. Fan temps depend on what T-stat you're using. Drop the temps by the same amount as the T-stat. Stock is 203°, so if you use a 180, drop everything 23°. If you use a 160, drop them by 43° (and expect it to throw a code)

That explains why everyone sells the 180 thermostat ... I have the mopar cai the new one that actually pulls cool air and is sealed off under the hood..
