Boost Gauge problem???
I installed my boost gauge and pressure tested the whole thing from the manifold connection to the gauge and everything works great. However, when I hook it up to the spot in the manifold, the gauge doesn't move. I reved it up and still nothing. Do I need to be driving for it to work or should I be reading something at idle?

but does that mean that at idle the gauge isn't going to move?

Also over tightening the compression fitting on the tubing will/may cut you off.

Flash is right, as usual. You can stomp on in just about all you want in park or neutral and the needle may not even move. Put her in gear and go climb a hill and TRY to watch it move! It'll jump pretty dang'd quick under load.

I took her out last night in the city (at work) real quick. I didn't get to open her up, but I got the boost gauge to move (phew) Now I am anxious to start tweaking her a little more!

I haven't had the chance to run her wide open yet (city streets), but she hit 18 when I let off. I am leaving work in the morning and am going to play a little on the way home to get more accurate readings...will post results after

Your 89's setup is similar to my early 91. You will probably be hitting around 25 to 30 psi on highway climbs with it pegged. The non-intercooled trucks develop more boost because of the plumbing the air does not have to run through. This is not that much of an advantage because of the higher intake air temperature of the non-ic'd engine. I love the winter only for the power boost we get.
