I don't think it would work seeing as how they are able to read 22 psi and not peak. The scale is probably too large for it to adapt. The ideal map sensor would hit max voltage at 9psi and still be around 1.7 volts at 22" vac. Anyone have any ideas... Maybe one off my wifes A4 1.8T would work it runs low boost. I'll have to check the voltage.
