Boost gauge

[waynieZ]

This is my first power adder build and I have a question about boost gauges. I'm using Auto Meter Ultra lite II gauges. Do I need a gauge with boost and vacuum or just boost or does it even make a difference? Max on boost down the road would be less than 15 psi. Mechanical or electric?
Thanks.

Mine is not electric and has both boost and vacuum. I think having both allows better diagnosing if something else is amiss.

Best to go with a gauge that shows vacuum and boost, better diagnosing down the road and you can catch any issues early.
Mechanical and electric is your own personal preference and of course how much you want to hurt your wallet, same goes with brand. I've used cheap brand boost gauges before and they have never let me down.

Thanks Evan I have Autometer UltraLite II's so That's what I'm going with. I'll probably go with the Vacuum and Boost.
