DQ, Whats the difference between a Mustang dyno and a dynojet?

[OneHotLX]

I have only two questions. First, on a Mustang Dyno can the simulations be turned off to get just a direct reading of horsepower like a DynoJet? Second, Turbolx, have you or anyone else actually had one car with the same tune on both a Dynojet and a MD? Did you see a difference in the HP ratings?(Note: I'm not asking whether the car was tuned on one or the other but whether there was a difference between the two dyno's HP numbers on a particular vehicle.)
