Uh, yea (I guess). Could you please write in sentences? This isn't a cell phone text message medium.
And, I just realized you asked a question at the end.
Other people have reported better gas mileage and power using 93 octane and the corresponding tune. I've never tried it. I got better mileage and response just using the 87 tune.
If you use 89 octane in an 87 tune, you should be able to advance your timing by 1.0 degree in the Custom Options, and that should improve both power and mileage.
