Which is 100% correct. Comparing one dyno to another is futile exercise. Even comparing the same brand dyno to another is not by any means scientific. This is why you must look at the DELTA between the runs... THAT is accurate.

It's obvious that a Dynapack is going to read higher anyway because it's not going to account for losses from rotating the wheels and tires. It removes a variable from the equation which I think is better. The less variables you have the more accurate the result.
Perhaps obvious to you, but not everyone. When they see a thread title that says 430 HP on a car people struggle to get 400 HP from NA, there needs to be a little more information on the dyno itself. I just wanted to provide some info so people can compare to typical Dynojet numbers.
