You will get all kinds of answers to this one, but I have ran some 400-500 HP cars at a controlled sweep test on a Mustang and the numbers were almost identical on a Dynojet. I think alot of people use the vehicle weight input on the Mustangs for Power Curve testing and that will get you numbers all over the place. There is no set difference, but some say 5-10%.
Again, if you want a high bragging number, make a slow pull on a mustang.(There are many other ways also toget a higher number)
The dyno should be used as a before and after test so you will know if you helped or hurt with whatever you changed. Use the same type,(the same dyno is best) the same procedure-accell rate, same weather conditions the best that you can as correction factors are not magic, etc.
