Boost guage question

[Mongoose]

When I first got my Cobra my boost guage would go to 10 psi under full throttle. Now, after 280 miles the guage only moves up to about 1/4 scale. Car seems to run the same though. So, is there a boost guage problem with some 2003's. If not I'll just worry about it till the weather gets better here in Ohio, and take it in for service. Thanks in advance.:wtf:

I don't think the boost guage is accurate I installed a autometer boost gauge and it reads differently than the stock gauge. Rachrse

You might want to check the connections and vacuum lines to the gauge. My stock gauge read just short of 10psi until I put the exhaust on. Then it dropped a little. When I put my Autometer gauge in it showed 6.5 to 7 psi and the stock gauge stayed pretty consistent with where it had been after the exhaust.

Other than it being a little inaccurate your's is the first I've heard behaving that way.

I found the boost guage line today. Passenger side of engine compartment close to firewall. Red and black hose joined together. Black hose goes to the guage. I did the air pressure check on my boost gauge according to the Shop Manual and it wants to stick low on the scale sometimes. Now I'll have to take it in and have them check it......whole guage cluster has to be changed according to manual :rant: :wtf:
