A couple Gryphon questions, what tunes and octane?

[Jackpine]

Paul, I think what you have there is fine. My only question is, do you really think you're going to use the 91 octane tune that much? Please understand you have to really run your tank almost empty before you fill with the 91 octane stuff to use that tune safely. IF, you are going to drive around most of the time with 91 octane (while you're at home), then it's fine.

And, there's no problem whatsoever in selecting an 87 octane tune with 91 octane gas in the tank - just don't go the other way, it can be hard on the engine to use a 91 octane tune with 87 octane gas.

I'm not trying to discourage you. I'm just telling you what I know Bill and Corey would tell you. Don't buy a tune you don't need. They don't want to see you throw money away any more than you do. Just ask yourself if you really need this tune.

I can tell you I've been VERY happy with my two 87 octane tunes.
