I just purchased a tuner and 3 tunes from MPT. I'm not exactly sure which 3 tunes I should select, though. I normally run 91 octane (it's definitely most readily available here), so I'm going to get the 91 PR-X tune for sure, and I'm also going to get the Performance Tow tune because I do tow sometimes, but I'm not sure what to select for the 3rd tune. I think my options are either the 93 PR-X, or an Adaptive Any Octane tune.
I can't see ever putting anything less than 91 in the truck (I'd really have to be in the middle of nowhere that has nothing resembling premium at that point), so I'm not sure I want to go with the Adaptive Octane tune. But, at the same point I don't see ever running the tank mostly dry and then filling up with 93 (which is what would be necessary to run the 93, as you aren't supposed to run the 93 tune with anything less than 93 octane). It almost seems like the 3rd tune won't really ever be used, and would just be a backup for a "what if" scenario. I guess the Adaptive Octane tune would be a good fail-safe, should I be forced to run 87 sometime. If I ever put 93 in, the 91 PR-X tune will work just fine with the higher octane. However, the 91 PR-X tune will NOT be happy if I am forced to put 87 in it...
Anyone have any additional thoughts? Thanks!
