kx666,sorry to disapointed you a "little" bit!
I?m involved with my friends tuning of these A... sxv550,they put out in restricted form about 55 bhp and unrestricted with open inlet and changed fuelmap approx 65 bhp.
With new factory pipes and changed fuelmap,ignition and rpmstop at ~12000 rpm,
71 bhp BUT only approx 55Nm of torque,I got 70 bhp/70Nm!
Very easy tuning with computer and a program from Australia,TuneBoy.
A dyno,but not ours with not race allowed GPR pipe on(to much dB):
