Most important guages for boosted engines?

[LtNoogie]

Can I get a single combo Boost/Vacuum gauge or does it have to be boost only?

Does this mean that the intake manifold pressure will show max vacuum at idle and then swing to low vacuum at WOT (S/C not engaged) to boosted psi if the S/C is spinning?

It's been a while since I thought about how an engine functions.

I've seen those around, sounds like a good combo!

That's the kind I run, heck I even use the vacuum function the more vacuum you see the better your mileage!

This is the same one but I swapped the face and ring to black..
