Mosquito Magnum PETG max flow rate?

Mosquito Magnum PETG max flow rate?

What is the max flow rate in the Mosquito Magnum for PETG? I purchased the Mosquito Magnum with the impression that it would provide much greater flow rate than the stock Prusa V6 hot end. The most I have been able to reliably push through the hot end (with 0.6mm nozzle) is ~ 11.5 mm^3/sec.

Am I missing something, or is that about the right ballpark for PETG?

thanks
