we spent over 7 hrs on the dyno tuning the EFI in & the chart I have has just a short pull on it but it held over 360 Hp[612 gross] to the tires between 5100 RPM up past 6500 RPM with peak power between 6100 -6300 RPM , the torque curve is silly , it was over 315 tq [536 gross]from 4900 -6500 RPM & over 360 tq [612 gross] from 5200 - 5700 RPM
