I have the pipercross (non race).

Had the busa on the dyno immediately before & after installation. The after figures were better for Hp & torque, and the A/F ratio was better.

No tuning was done (don't have a PCIII etc) & I have the 2 bros carbon slip-ons which were on for both runs.

BMC for power, stock if you want to keep sh1t out of your engine.. There is a trade off for better air flow.
