I was asked this question, so i will post it here. How can a Tunze propose that they move 3000-5000 gal. an hour when a Sequence pump of much larger size moves the same amount. Are these false readings or do they interpret the flow readings as water around the stream produced moves along with it causing movement also. If you were to fill a 1000 gallon container and hook up a Sequence pump to it, and time how long it ran to empty it and then somehow hook up a powerhead to it, i believe there would be quite a difference. What are your guys thoughts?

You should post this question in the Tunze Forum. Roger V, the Tunze rep knows his equipment pretty well and would most likely post a reasonable answer to your Q.
It has to do with the propeller used you see.
A propeller with an open designed shroud will move far more water and do it much more efficiently than a regular flat bladed impeller. The analogy is like a paddle wheel boat versus one using a propeller.
A propeller is designed to move water while an impeller is designed to suck in and pump out water.
If you put your hand infront of a Tunze or MJ mod or SEIO, you will see and feel that the flow is quite gentle and wide and dispursed. Whereas the stock pump would put out a much narrower stream but feels much stronger.
