Anyone else have this problem.

Tonight my boost/vacuum gauge stopped working. It sits right below 0 and when you hit the gas it sits right on 0 and doesn't move from there. I noticed a whistle and a whine that I have never heard before. You can hear the whistle and whine from idle all the way to about 1200 RPM. The truck still runs as strong as it did before the problem. Also noticed a quick knocking like sound coming from the supercharger(or in the area of). Any ideas? Anyone else have this problem? It started doing it about 30 minutes ago.

Check your boost guage lines. I would also check the lines if you did the boost by pass mod.

yeah, i would check your boost gauge lines. or just get a whole new gauge setup......the stock ones are not accurate.

Thanks guys!
One of the lines from the boost by-pass mod came out.
