Ported blower=increased MAF voltage?

[YGETV8]

I only saw about a .03-.05 increase in MAF while datalogging, but am pretty convinced my clutch is now slipping some. MPH was up 2-3 in the 1/8 but same in 1/4. Am hoping if the clutch is slipping, the load would be less and not reflect an accurate MAF increase since I thought this would help define if my self-port job was effective.

Can anybody share some data from before and after ported blower install?

Thanks,
