What are the best tune settings for diablo sport on an automatic gt 2005. I am currently using th diablo preformance tune but still seems not the optimum. Any ideas or numbers to the optimal settings for gear,sparktiming,rmp etc etc....

Not everyone has that kind of money or even a dyno in their area. I don't.

Well, the Diablo contains 3 different tunes. It doesnt contain one clearly marked as 93/91 octane, though it has an 87, 89, and Performance tune. He (and I) are both confused as to whether the 89 or the Perf tune is superior, it would seem.

The performance tune is the 91 octane ( premium unleaded ) tune. Unless stated otherwise ( like the 87 and 89 tunes ) all performance tunes require premium unleaded fuel.

That's what I was figuring, just wasn't quite sure. =) Thx

All the Diablo tunes are conservative. If you don't have a tuner/dyno in your area - there are a lot of companies (Brenspeed for example) that will send you a tune based on your mods that tune with a similiar set-up car at their shop. You should always carry 2 tunes in your predator - 1 for street and 1 for race. The diferrence in a custom tune is enormous.
