Pipercross

     In our R&D before deciding to import these we tested on a 2005 GSXR750 that already had cams and a full exhaust system. We took the 317-004 Power Commander map and then maximized it for the Pipercross airflow...but to be fair to the OEM filter we also max mapped the OEM filter to pull more air through with more fuel flow (so it wouldn't possibly run lean like some bikes come from the factory). With Pipercross, we gained +2hp with the street version and +3hp with the race version. The new BMW1200 saw a +8.5hp midrange gain from using a Pipercross filter alone!
