I have the electronic digital boost gauge from Cyberdyne. It is obvious that this gauge is not going to last and reads inaccurately. So I doubled up and put on an Autometer ultralite analog gauge. The stinkin thing reads 3lbs when the motor is off and it jumps around 5 lbs either way when running. So I bought an Autometer liquid filled 2 5/8 gauge but when the gauge is set on a diagonal angle, ie: my handlebar mount, the fluid level goes right through the upper half of the gauge. Anyone experienced this? What do you do? I thought about running it upside down so the level goes through the vacuum which is not important to me.

I don't think any of these guages are built for the snowmobile environment .
I have a digital dual boost and egt guage. It never worked from the start. The EGT part seems to work fine, but the boost guage never has worked.
Low boost shows a peak of 11lbs, and runs 7-9lbs. High boost in about 100 ft showed 23lbs peak, and runs 14-17lbs. Shut in down because I was only trying to see if the boost switch was leaking.
Bender sent me a new transducer and that did not fix it and Bully Dog said they would sent me a new guage.
The memory feature is real nice though.

Because it looks like crap with the fluid level going right through the important area. I dont know why they couldnt just fill the thing up all the way!

Here's the skinny on liquid filled guages.If they are good ones they should have a small screw at the top,you loosen this to adjust it to the pressure of elevation.Because it's liquid filled it is sensitive to pressure because it's sealed.

gage,s
hears why L Q gages do not like a cold enverment the liquid is a very thick oil (for dampening the needle movment) when its cold the oil real gets thick not only does the gage not work but because the needle not move but with boost on and cold gage this will ruin the calabration in short order. been there done that in my trade we change gages at lest once a year and a gage is run in the middle of its travel is the best ie if you need a gage for 30 lb get one that goes to 60lb

I use the liquid-filled Autometer gauge as well. The line does annoy me somewhat, but the gauge works fine for my purposes.
Loosening the bleeder screw on the top of the gauge to "zero" it from time to time is of utmost importance.
