performancetune for my mustang GT 206 conv

[hans]

Last week I tried the 93 and 91 performance tunes on my 2006 gt with borla catbacks and K&N airfilter. It worked out quite well. The 93 tune proved fast, with no pinging, however the engine felt less smooth and a little distressed. I feel it was on the very limit of its advance curve.The 91 tune however proved to be perfect: smooth like the factory tune at low rpm, but much more pulling power, particularly from 3000 rpm . I would recomment the 91 tune for street use. You also keep a save margin for fuel quality and you hardly loose any power compared to 93, (if any).

What octane fuel are you running? The timing will be more advanced with a 93 tune.

93 .I know this tune ifor 93 is moe advanced. That's my point. The car runs better with slightly less advance. So i run 93 and use 91 performance tune
