2008 Mustang Bullitt

[drakorosus]

I have a 2008 Ford Mustang Bullitt. I’ve replace the bullitt’s stock cone filter with a better flowing k&n cone filter of the same size, I also change the axle back to FRPP M-5230-GTA . I just got my predator U7145 9r03 and I loaded the 91 performance tune because there is no 93 octane gas in AZ.
I there fuel additives that I can used to be able to load the 93 tune?
Can I modify the tune to take advantage of the filter and the exhaust changes?

Thanks for all the answers!

I have an 09 Bullitt with ford racing exhaust, stock everything else. It is really powerful but I always want more. How much more (if you have dynoed it) have you gotten out of it by using the predator? Can you tell a difference in power or mileage? I know these cars will adjust the timing advance based on what fuel you run in them (factory tune) so I am not sure where you can gain from the predator. Just cursious and because it is a relatively rare car, probably not too many people tuning them. Look forward to hearing from you.

You'll see solid 15-20 rwhp gains on the Bullitt.
