Volumetric Efficiency

Has anyone ever checked the Volumetric Efficiency of their 5.6 engine? See here for an online calculator and explanation of what the VE is https://www.otctools.com/ve -

I just plugged in my numbers from the last time a ran a WOT Uprev log - My number are -

68F temp (20C), 5738 RPM, 221 MAF gm/s and of course 5.6 liter engine which = a VE of 61.

That seems pretty low but I have nothing to compare it to - so I hope some of you can run the numbers for comparison. I am especially interested in the max MAF gm/s reading on a stock intake. Edit - also max MAF voltage.

I have the JBA headers and Cajun high flow cats into a stock exhaust. I did have an S&B intake but have since switch back to stock. I don't remember if the WOT pull above was with the S&B or stock. I plan to pull another log when I get a chance.

Thanks for any feedback
