only a couple of question though, i tune my car at 93 octane. is that were it supposed to be? i can choose from 91 92 or 93. what do those number mean? when i go to the gas station i only see 91 premium gasoline but never 93. no engine light has come on but am i doing this tuning thing correctly?

Since, 91 is the highest available, you should be using the 91 octane tune. Putting 91 in the tank with a 93 tune won't throw a CEL, BUT it could cause knocking/detonation issues. This is not good. With the 91 octane tune installed, you could put in a higher octane gas with no issues if it was available to you, just don't use anything less than 91 octane if that is the tune you have installed.
First things first, Thanks for your feedback. I'm glad to hear you're in good shape and really enjoying your Bama tune!
You definitely want to run the 91 Octane tune if that's the gas you're running. If there was 93 Octane available in your area then it would be completely safe to run the 93 Race tune. However, you never want to run a lower octane then the tune calls for.
