Gauge Wobble

Hey I need some help if anyone has suggestions? I have Auto meter sports comp gauges and my boost gauge starts to wobble and flicker threw the boost levels starting at about ten and all the way up... It will flicker between about 5 pounds back and forth...is this due to where the sensor is mounted? I heard I can use a liquid filled gauge but I do not want to dumb money for more gauges.... thanks for the help!!

i have the same issue and done some searching on here and everybody seems to say that you need to install a 90 deg fitting in where you teed in to map line or put fitting in intake spider. there was also an article in diesel power magazine where they got 500 hp out of an obs they used an autometer fuel snubber to stop that in the boost gauge. i haven't gotten around to putting a 90 in mine to see if it helps yet

Does it make a hissing or clicking noise too? I had that with my Isspros. Got a package in the mail from them out of nowhere one day, and it had a little brass fitting in it that goes in the back of the gauge. Basically it had alot smaller hole in the middle than the original one. Chokes the airflow down a little. Fixed my issues

My boost gauge was t-d into the map line and it would flicker. So i moved it to the intake spyder and i have had zero problems since

95redrifle when you put yours in the intake spyder did you just drill and tap a hole in the spyder or weld a bung in. wondering if the spyder is thick enough to get enough threads to seal properly? i put a 90 in my tee in map line helped but still have flutter so looking to redo it totally

Yes i drilled and tapped the spyder. You have to be careful where you put it because like you said it is too thin in some spots. I put some plumbers tape on mine and it seals just fine. You can see in this pic where i put mine.
