I think 15%-20% is way off. The difference between Dynojet numbers and Mustang numbers (arguably the dynomometers with the biggest disparity) are typically only 5%-8%. So this would mean that Superflow dynos measure 10%-15% less than Mustang dynos, which I seriously doubt.

 

Take it from the Dyno Pro!

Yeah, 15-20 sounded like too much, and Allen showed me a dyno of a stock truck which made 230, and I think people usually see close to 250 on a Dynojet (If I remember right) which would be about 8% difference. Although we all know different trucks dont make exactly the same power, so I dont really like comparing to some other truck's stock numbers.

And if it was 8% more, my Dynojet numbers would be 365/424, which I would still be happy with, especially considering the heat and humidity.
