All the reviews on this unit are for the AFR gauge that I have seen. Not the boost gauge displayed. I stalled unit and it was not reading properly. It showed 0psi when motor was not running but once engine was started and idling, it displayed -8 psi at idle. Seemed way to low for idling so I checked with a calibrated vacuum meter and engine was only pulling -3psi. Couldn't find any instructions on how to adjust the meter. So I just took it off. Worthless if unit does not display proper vacuum/boost levels.

This gets a better reading than analog, no lag. Looks great, love the digital needle sweep.
