I am looking to purchase a set of dual aeroforce gauges for my 2014 GT500 and I was wondering if anyone knew if they would display "boost" right out of the box by just plugging them into the OBD2 Port?? Thanks...
Aeroforce Gauges show boost?

No. They require an external sensor to display accurate boost readings.
That's a bummer, thanks for the quick reply.
I'd get a separate dedicated gauge. When you're under boost and you want to see what it is, some views on the Aeroforce gauge may not be showing what you want when you glance over at it.
You probably make a good point. Do you have a separate boost gauge and if so, how and where did you connect for boost?
I used to run a standalone boost gauge, but ran out of room. Running dual Interceptors with a boost input and a standalone fuel pressure gauge now. It works just fine for me....I simply leave one of the 4 available PIDs set to vacuum/boost at all times. Not a big deal as there are 3 more I can set to monitor whatever I want at any given time. I also like the fact that it gives you boost as a numerical value. Most of the other boost gauges, even the electric ones, use a dial which can be very hard to get an accurate read on when you're WOT and trying to keep it on the road. It's easy to get a quick glance at a numerical value.
The sensor requires you to wire it up to 12V switched power, which you can pull from the passenger side fuse box, there are several unused slots there. Then you plug it into the analog input on the back of one of your gauges. So even if you have a dual Interceptor setup, the boost reading will only be available on the gauge you plug the sensor into.

Guys--Thanks for the input, especially on the power. This is probably a stupid question, but where do you tap into the car for the boost reading? Is there a guide where someone has already walked through this? I searched all the forums and could not find one. Again, sorry for the simple question and thanks.
Here's how mine is tapped into vacuum. I have a tee between the fuel rail pressure sensor and the port on the front of the intake manifold. The vacuum line going down goes into a 1/8" vinyl tubing that goes to the MAP sensor by the firewall.

I'm tapped in at the same spot. Since I have to make multiple connections that reference boost, though, I then route that line to a Fore boost manifold bolted to the firewall. It's a nice piece and has about 5 ports to make other connections. If you think you may upgrade to cams, return fuel system, or anything else that may need a boost reference it may be worth your while to get one now. Cleans up the install and prevents you from continuously teeing off of lines.
Thanks for the info. Do you have picture of the MAP sensor by the firewall?
If you're running an electric boost gauge it's just the sensor that comes with your particular gauge, they all look different. The vacuum line plugs directly into a barb on it, then you run your wires to the gauge. If you have a mechanical boost gauge you'd simply run the vacuum line directly into the back of the gauge in the cabin.
I run my vacuum line through the driver's side firewall into the cabin and plug it into the sensor there, where it's zip tied to some wiring harnesses under the dash. All that is up to you.
The sensor is not very big and what RBB stated is correct. The sensor was supplied with the gauge. I have yet to fab up a permanent mount for it, so it's just zip tied to a couple of holes in the fender. I always tend to find more important projects to work on than that one. I do have a few analog inputs on my Aeroforce gauges and between the boost gauge and the analog power sources, I came up with this fuse block to hook them all up. Voltage draw on all these wires is very low and my power is an add-a-circuit in the fuse block under the dash.
Pretty cool solution for multiple analog inputs with the fuse block there, John. I like it.
Unrelated, do you have that car back on the road now?
Thanks, I'm using a temp sensor in my intercooler line out of the heat exchanger and an oil pressure output for my Aeroforce. I also have the boost gauge on an Autometer LED dimmer control, all of which require a power output.
Yes, the car has been back on the road for a couple months. It's been a bit of a struggle to tune it like I want, but I'm finally there now.

Here is my gauge setup and what I normally monitor. I have a MAP sensor for boost also. I have the PID scrolling (scan or cyclic scan) feature disabled on the AeroForce so I can monitor desired PIDS full time or manually select whatever PIDS I want to see at the time. One great feature not mentioned is display RECORD for 45-60 seconds, triggered by WOT, then you can play the run back frame by frame. It's a good way to make sure things are working correctly without capturing a full datalog.
I chose sweep gauges in my line of sight for fuel pressure and boost. I would want to see a loss of fuel pressure or spike in boost so I can get off the gas as quickly as possible to avoid engine damage.

Similar to RBB above, I elected to utilize a mechanical boost gauge which required threading the supplied plastic vacuum tube all the way through the firewall directly into the triple SOS pillar pod housing the Autometer boost gauge. The angle was tricky because the vacuum line must not be kinked, but I was able to successfully navigate the radius. The vacuum tap utilized the fuel rail vacuum line as several of you used, and I opted for a heavy duty brass fitting. This installation has been problem free since I initially installed this in early 2015 - the plastic vacuum tube supplied by Autometer has proven quite sturdy.
Though not part of the discussion, in this picture you can see that I also utilized a Metco fuel adapter block to add an Autometer electric fuel pressure gauge, which is shown in the gauge pod picture below.
