Finally got around to filling up with 93 octane and loaded the 93 tune from Brenspeed. I have to say there is a gratifying difference compared to the 87 tune. The launch is more agressive with a little more tire spin, maybe 5 to 6 feet depending on the street surface. From a stop sign turning to the right, flat out smokes it. Acceleration at highway speeds is also improved. Now we'll see if the mileage goes up. I've been getting around 20 to 20.5 with the 87 tune which is an improvement of approximately +2 from stock with my mods. If the 93, or even the 91 tune picks up 1 mpg or so more, that'll be a benefit in addition to the performance improvement.

Just out of curiosity, have any of you using the 91 or 93 tune seen any mpg gains?

Thanks for your input.
