Hi everyone I have a few gauges that my dad got with a cheap ebay turbo kit he bought and I was thinking about using the boost gauge because it kind of my matches my afr gauge. I would prefer to see someones experience from using one and not of people dissing it because they bought something more expesive. Do they read off? Any comments appreciated

 

heres what i would think, find someone in your area with a known good gauge and hook both up and drive around and compare.
