No canned tune is going to be the"fastest". The only way that will happen is some time with a datalogger. Each bike, although they are built on the same assembly line, is going to be a little different from each other. The same goes for add on parts.
You could always try calling someplace like Fuel Moto. Chances are that they've tuned a bike running that particular combo. But they will probably want money for it.
The flow difference between slip ons is slight enough that I doubt you'll notice much of a difference by using the Leo Vince tune.
