Just thank God he has gone.
Here is the correct data from the horses mouth (ElsaWin)
Your new values look fine at idle, if a bit high. I have seen around 8g/s at idle recently too.
285g/s looks good too at 5000rpm. Plug in VAGCom and select log values and go for a little run, make sure you hit the red line at least once, then plot a graph in excel.
I found a old graph from my previous MAF which was working ok (as far as I know). Rpm/100 for easy comparison.
