Her Shadow was off by approximately 5 MPH. Some have mentioned changing gear ratio, but I believe that it's just the nature of the beast.
My wife and I did the same thing...
She drove her Chevy Cobalt at 70mph on a section of the interstate. Once it was safe to pass, I cruised up in the next lane and aligned myself with her side-by-side.
Chevy Cobalt ===> 70 mph
Shadow Aero 750 ===> 75 mph
