Higher Octane Fuel Use

[mxja05GT]

I am based outside the US, my 05 Mustang GT which is also produced /built outside of the US, which I ahve been informed by Ford has some diffences to the North American built car.
The gas avilable is 97 octane fuel. What % compensation should I use for the fuel air ratio when tuning with the DIAU 7140 Flash Tuner.
I know of some people who have re-tuned the 05-07 Mustang using a Diablo Flash Tuner with some success, but I would like to be more informen before attempting.
By the way, I purchased my flash tuner from the USA, from BrothersPerformance.com

I would like to get the FA mixture correct and at optimimum

Thanks.

I hope this is the correct format, but I need the info now. If it isnt "ups" but I have only just registerd with Diablo[/b]

There is no need to modify the tune for use with higher octane, but you may be able to find a bit of power by raising the global spark parameter by about 5%.

Thanks
