Difference between 91 tune and Diablosport tune

[hans4real]

I'm tuning the '11 SRT8 Challenger and my tuning options are not the same as the other years. There are 3 choices, basically reads from top to bottom - Diablosport tune, 91 oct tune and some other stock tune. There is no description of a 93 oct tune or a CAI tune. I'm okay with that just want to know what each tune is designed to accomplish.. Can you please describe the main differences in the tunes? Or point me to the thread that has already covered this topic.

Diablo Tune is the 93 Octane tune.
