There is a brain box that a vac line goes into, then it sends the reading to the gauge.

With a mechanical boost gauge you have to run a vacuum line all the way to the gauge (ie through the firewall into the cabin).
With an electronic boost gauge you only need to run a thin electrical wire through the firewall.
I love VDO gauges cause you can go to junkyards and find them in porsches and sabbs. mine reads 30hg-15psi perfect for a mazdaspeed. I love when people buy a 30 psi gauge and only run 7-8 psi, and better yet get it in BAR wtf we live in america we don't know how many bar our tires are supposed to have

The vacumn line is very thin and easy easy to go through the firewall.

Dude I've been saying this FOREVER....well 3 months. I have a 15 psi gauge and it's MORE than enough for the Speed.
The autometer gauges are used in many real racing situations with tons of accuracy. Way more then even we need on the street.

A 3/16" vacuum hose is a lot thicker than an insulated 18 gauge wire.
The wire is even a lot thinner than the thin nylon vacuum line supplied with most mechanical boost gauges.
Yeah, it's easy to run a vac line through the firewall (I have a mechanical gauge) but it's even easier to run one single very thin wire.
"The wire is even a lot thinner than the thin nylon vacuum line supplied with most mechanical boost gauges."
The vacuum line is just as easy. I have done a ton of wireing and I did my first vacuum line with this boost gauge. It was very easy. I did not even have to open the hole. I placed it next to the cheese amp power wire and pushed it right through. If anything it's easier than a wire because it's a bit stiffer which helps to push it through.
Don't get me wrong the Defi gauges blow away the Autometer in looks with the back lighting but I don't have that kind of cash. Baby forumula is $23.00 a can , he goes through one a week. Plus I feel like that money can be use to make the car faster. Higher priced 94 octain gas, plugs, boost controller.
"ive heard alot of people complaining about autometer... ive heard no one complain about defi nor any of the other japanese brands"
Ok so there is no proof.
