Earlier in the week, i dropped my GT off to have the fuel pump TSB performed. I was told to try to leave with very little gas in the tank so it would be easier on the tech. Well, the salesman, who is a friend of mine, was gonna deliver my car to me this afternoon at work. He said they'd put just a bit of gas in it, wash it, and have it to me by 5.

The problem is this.....i have a CAI with the bama 93 race tune. i didn't even think to remind him, so he put 87 octane in it. After he dropped it off, he said he put 3-4 gallons in it so by my approximation, it should have had about a 50/50 mixture of 93/87 octane gas. He drove it about 25 miles. He said it didn't hear any knocking or pinging, and there weren't any CELs thrown. Am i ok?? i quickly loaded my 87 tune back and will keep it until i run enough 93 octane through it. It sounds ok now, but i'm worried about unseen damage. What are the dangers here??? Am i ok??

shouldnt cause any problems unless you are taking it to WOT,,,,,

You're fine. Drive it nice and listen for detonation. You can always use additives to get the octane level up, but typically those additives have distillates that can harm fuel system components...not to mention catalysts....but I don't know if you even have them still....

Either way - if you can't hear detonation - you likely don't have anything to worry about. The only reason your tune requires it is because of the massive amount of spark advance it will dish out. Drive it like a wimp for a tank and you should be good.
