While living in Savannah Georgia (sea-level) I installed a Demolet CAI with an excalibrater II tune for 91 Octane. the tunes included wer 89, 91, and 93. I had no problem finding 93 Octane to fit the Demolet specs and felt a difference in my power. I tuned for 91 to compenstae for any fluctuations in the 93 Octane gasoline (err on the side of caution).
I have since moved to Denver, Colorado (5000+ft) and because of some science mumbo-jumbo altitude BS they do not produce 93 Octane gasoline. The highest one can get is 91 Octane. Consequently, I had to tune my car down to 89 in order to compensate for the lack of Octane. This begs the question of whether it is even worth it anymore to have the CAI if I can't use a quality tune with it.
Does the altitude compensate so much that I could safely go back to a 91 or even 93 tune with the 91 octane present here?
For example, I knew a guy who had an eclipse a few years ago that required he use premium gasoline. That's all it said, it never mentioned an octane. Even though there could be a significant difference between the premium octane in Georgia and Colorado. Surely the car wasn't damaged for using lower octane fuel in Colorado, otherwise they woudln't be able to sell the car here. Right? So theoretically, I could use a 93 tune with a 91 octane because of altitude here in Colorado... maybe?
Some big brain help me out with this.
