don't expect huge power gains from the pc111 maybe a pony here, a pony there... do expect an incredibly smooth and very responsive throttle.
sutton and his crew (zach & loren) set up my s4 very nicely... it's never behaved so well. i am happy have them wrench on my ride.
if you ever call you'll fall in love with wendy and that australian accent. and i was absolutely helpless when i walked into the store and saw all the pretty shiney stuff in the shop. beware, loren is an excellent salesman. my wallet does hate me for the extra goodies, barnett clutch basket, cams, re-sprung-valved forks; but the beyatch has never ran so well.
really nice folks yet very professional when it comes to anything ducati.
