I was looking for a performance upgrade and ran across this web site. Are the HP numbers correct? What about the quality of this product.

I've never heard of them. It does say max power to flywheel. Most other companies advertise max power gain at the rearwheel. Most likley by the time you consider the power loss through the drivetrain you might be a little better than an Edge EZ can gain. I think Bully Dog advertise about the most gain (rear wheel) using the Power Pup or Torque Dog modules. TST and the Edge Juice are also out for the 600's. Very promising gains there too.
