Boost guage problem?

[bryanmoore@classicnet.net]

Just installed a pyrometer and boost guage. The next morning I let my truck idle for about 5 minutes to warm up. When I took off I noticed the boost guage was fogged up. When I got on it to see if it was working correctly the needle fluttered pretty bad throughout the range of the guage and especially bad the higher you went.

After about 15 of driving the fog went away but the needle problem remains. Is this a defective guage or hooked up wrong? I tapped into a vacuum line near the MAP sensor. I contacted Auto Meter and they said they would be happy to try to repair if I sent it back. Should I try a different location.

Thanks

On the 6.0 the only 2 places I would use to get my boost readings are 1) the intake elbow. 2) the obd2 port. The map sensor is said to not be reliable.

AGREED! Move your boost line to the intake elbow and you'll be fine. As far as the fog in your gauge, make sure your bulb socket is in the back of the gauge tightly so it seals out the cold as good as it can. My buddy had this happen after he changed the bulbs and that was it.

Good luck
