Like all aftermarket shop dyno's, it's key to remember they're relative to each other. The important part is that you go back to the same dyno with the same operator and they run the numbers with the same correction so you get a reasonably accurate delta between modifications.

Thank you for the feedback.
Okay, but what's the difference between the SAE J607 and J1349 formulas? What parameters are different and how does that affect the measurement? "More realistic" doesn't mean anything to me.
Can you point me to a reference or two where I can read about these standards and how their methodology affects the outcome?
