I think i have a problem with my boost gage. I have an autometer ultralite boost gage. The problem is when the truck sits all day while im at work it doesnt seem to work at first. For about the first 10 of the drive home it doesnt move at all, and then all of a sudden it will jump up to 10 or 12 psi. It seems like the hotter out it is the longer it takes to work. Any suggestions on what might be wrong?

SSNIGHTMARE,

Sounds like it is sticking for some reason, they have a 1 year warranty and are easy to work with, get it replaced and you should be OK!

i have had the same problem, i found that the line (hose) running off the the gauge was to tight going into the back of the gauge. Therefore not getting enough pressure until about 10-15 psi and the temp factor because of the plastic and heat. Just besure to cut out the old place that went into the gauge. And replace the pill that crimps the line. It solved my problem if not call who you got the gauge from.
