For the same DynoJet at the same time my runs usually vary by only about 1%. Now at different times and atmosphereic conditions using the same Dynojet and using their software to create similar conditions (S.A.E. conditions), my readings vary by maybe 5% or more from one session to another. In short, I really don't trust the Dynojet software that creates the S.A.E. numbers. I always ask for the raw numbers and then use my own software to get either the sandard hp/tq readings or the S.A.E. readings that I want.

I have no experience with the Mustang dyno at all.
