exactly. ROUSH would not understate the horsepower of a car by 70 horses a good dyno tuner can make that screen say anything

I disagee, muscle cars have a history of understating a cars horsepower. This was especially prevelant in the 60's. A perfect example was the Shelby 500GT KR, it was rated at around 350hp, but in fact had over 400. I has to do with insurance. It is more costly to insure a 600hp car than a 500hp car, so the manufactorers take that into consideration when posting numbers.
