DFW Dyno Day 10/10 - Toyota Yaris Forums

Yeah, people claim that the Mustang dyno reads lower than the Dynojet, pretty universally. But there is also debate as to which one is more accurate. Still, there is no consensus on how much, and every A/B comparison I could find on the web involved cars with 3-6 times the HP we put down, so its not really apples-to-apples in simply figuring a %.
I think you can safely assume that you'd run a higher # on a Dynojet, but what that actually means, I couldn't say.
At this point, I'm sticking with the stated #'s. I seriously doubt its off by more than 2-3 HP.
