I have done hundreds of flow tests with various port/head/relief configurations. Your numbers are strong representatives. It is allot of work to get 150CFM @ 28". There is a point at which the valve can be completely removed and no flow increase detected. Without finding my records I seem to recall the stock flows to max out at 90 CFM. If I get in the mood I will try to find my notebook.
