Definitely get the one with the vacuum, Sean. You'll be able to monitor
the vacuum leaks, if any.
Mine is hte -30"Hg vacuum to +25psi boost VDO Cockpit White ($45) in the
Autometer A-pillar holder, the A4 application ($20).

I tapped into the 5mm green vac/boost line in the pass footwell. That's
where the ECU gets it. I suggest you use the quick disconnects from
McMaster.

I personally feel it's an overkill.
