New Gauges Installed! What the???

How we doing out there? I just got my gauges and A pillar installed this morning. I put in the boost gauge and the air/fuel ratio gauge. I did not do the installation, I took it to a speed shop in the Orlando area. I did not want to attempt doing it myself, I would probably screw something up. Anyways, I love how the gauges look, it turned out really good I think. Take a look at the pics. below and tell me what you think.

Driving home from the speed shop, I was watching the two gauges and seeing what they were doing. The boost gauge is nice. I hit right around 5-6psi, which is fine with me seeing the car has no modifications yet! Then I noticed the air/fuel ratio gauge and I was concerned. Now, I have no experience with this type of gauge, but the behavior of the gauge seemed weird to me. Basically, the gauge bounces back and forth between lean and rich a million times. The only time the gauge is not moving, is when I am coasting. Even at a red light, the gauge is moving all around. I did notice that when you get on the car, full throttle, the light is buried at Rich and stays there until the throttle is let off. I just can't seem to figure out why the gauge is doing this crazy behavior.

So, my question to you all out there, is my gauge installed wrong or is this what an air/fuel ratio gauge does?? Is it supposed to bounce back and forth a million times while driving and while at a stop? If this is the case, what is the exact purpose of this gauge? The reading can not be depended upon, because all the gauge does is move all around and never give a constant reading (execpt at full throttle when it reads a full green and does not move).

Any responses to this thread would be of help. Thanks for taking the time to read this and please, let me know what you all think!!

that's exactly what it should do, it also won't bounce around for the first minute or so of the car being on. it's really only useful during wot. and next time, learn and do the install yourself. you'll never learn if you don't try :) gauge install (at least these gauges) is very simple and helps you to at least identify where things are under your hood, and if worst comes to worst you just put things back to how they were and then pay for someone to do it, no harm done.
 
I bouth the gauges and the pillar from Jegs.com

The pillar is called a Dual Gauge Pillar(Full)

All together, for the three items=$165
 
the installation was $160, took about 3 hours of labor to do the job. It was well worth it I tell ya!
 
catches the oil from your pcv so the oil doesn't get back into your intake and get the inside of your pipes/turbo/intercooler all oily and helps them to keep their efficiency
 
actually, you can replace our stock coolant bottle to this catch can and it will look much nicer!!!! :D
 
So, I have come to the conclusion that the Air/Fuel Ratio Gauge that I have on my car is installed right. Some folks here have said that it is supposed to jump around all the time while you are driving and I did some research and they basically stated the same.

Here is a night shot of the gauges, the pic. sucks but I decided to post it. Oh well :D

As you might know already, the gauges do look good at night regardless of what the pic. shows. The gauges are easy to read, which is a definite plus!!!!
