Any vibrations from having the gauge mounted like that will fluctuate it also. Try holding it in your hand and then drive and see if it flutters under load.

You will all have to forgive the dumb question, but what do you do with this gauge? What do the numbers mean, and what do you use to get MPGs from that?

I am a noob at this thing too. But from what I have seen in the first full day of using it. When you accelerate try to keep vacuum as high as possible, a 1/4" of throttle changes it alot. Basically from what I figured out so far the higher the vacuum you hold the better the mileage. Keeps from you from putting engine under more "load" than needed. More load = more gas. Someone correct me if wrong.

I just seen you hit 51.07 on 22nd, I hit 51.05 on 23rd. Congrats.
Nice hitting that 50 mark!! Let's see who hits 55 now. Just friendly competition.

You are on!!! I fear I might have an edge, though. I found out today that my alignment was real bad. My rear dvr tire was kicked out 2 inches (former owner's accident). I was, in effect, dragging the tire. It's fixed now, so here I come!!!! slowly...

Oh no, you are still on dude. I am trying to get some coroplast and start on some cool stuff, but in a small Tennessee town it's like asking for the nose cone for the space shuttle. Maybe I will try a larger town, like Memphis.

I love what you have done so far. How did you get the pizza pans to stay in?

I took a compass to make a circle and drilled holes to match the high ring in center of my rim. I then drilled for the valve stem. And drilled and tapped rim for a #10 machine screw. Worked out really well but make sure you have pan perfectly centered to not disturb balance too much. Ohh and they are only $2.44 at Walmart Paint them or they will rust.

Tried this no change. If I slightly pinch the hose in my fingers it stops vibrating and still operates. Is there a buffer of some type I could put in the vac line to it. I thought about a small inline fuel filter. Would let the air through but slow down fluctuations. Would that work? I think a lot of it has to do with it not being a good vacuum gauge too, was on a hand vacuum pump. Not meant for this I am sure.
