I have tachs on all my rigs, along with vacuum gauges. I think a vacuum gauge is one of the best gauges to have for engine diagnosis.

How is that? Detection of a leak in the system, obviously, but what else?

Really? You can diag all kinds of issues I don't have time to type into this reply, as well as using it as a fuel-mileage gauge.

For example:

Reading your vacuum gauge

Now that's cool!
Never knew that.... Interesting.
 
For most modern engines? It's kinda nice but far from necessary..

Your motor won't let it over rev ;)

I agree, it's a reliable, well built chevy 5.3. Bounce that F'er off the rev limiter!!:steer:
 
VDO supplies to most german automakers including Porsche, Audi, and BMW (okay, theyre bavarian). I've run them in quite a few cars, have a set of Stewart Warners for my moms corvette, and ran Autometers in my dads street/strip car. They all performed equally.

Fun fact: Sunpro is owned by Snap-On, their tachs are nice for the price.
 
I like Stewart Warner, I have one of their oil guages, and it's built, plus the quality and support is always there.
 
I bought various gauges from these guys. I have them installed but since I havent fired my motor they havent been used yet although the light up real nice. I think they seem reasonable for the price.

I've had Glow Shift gauges in my diesel pickup for about a year now. I added five gauges and they are all working good except for the fuel pressure gauge. I just found out that it maybe should of had a snubber in line before the sending unit. It also has done some screwy things with the color shift. But, overall I'm satisfied with what is maybe not as good a quality product as something like Autometer, but much more affordable.
