hack/ experiment press range of MAP sensors?

Anyone have any idea what the non-design/ experimental/ hack vacuum pressure ranges are of typical automotive map sensors? Do any of them go into deep vac readings? A quick search (the usual google stupidity) is not much help

Not so much interested in the positive pressure end but the vacuum end

I did find this project, but unless I mis-read something, he is really really pushing the published limits of this sensor
