Mustang is the dynamometer of choice for serious performance tuners and aftermarket product developers for a reason - they know the facts. Fact is - in order to get the best tuning results, you need a dyno that applies an accurate load, like the car would see on the road or track. Other dynos don't compare and will give higher horsepower readings to try to impress.
But if the power you thought you found on your dyno wasn't based on actual real-world loading, chances are it won't be there when you need it at the track. The best tuners and power product developers in the world know the facts - Mustang Dynamometer is the most accurate and reliable dyno because it provides real-world loading and precise control.
