Dynoed the VTT G80 M3C. It's definitely underrated. Depending on the correction factor or lack thereof showing between 455-481WHP/445-467WTQ, which is about 523.25-553.15 to the crank. So between 13-43hp underrated depending on if you want to run SAE, STD, or Uncorrected. The Factory almost certainly rates it SAE so it's not too far off there. If you go uncorrected it's quite a bit underrated. Take it as you will...
