Yup, that's what I've heard from my DynoJet guys. The Mustang is programable for correction while the Dynojet software does the correction factor automatically from the software and a thermometer.
BTW, I don't believe that the DynoJet correction factor is really that good. It gave me a +1% from actual when the temp was 106 F. Thats correction to SAE which is supposed to be 77 F. Atmospheric pressure and humidity are completely ignored in the DynoJet correction.
Both dynos probably both have shortcomings.
