It sounds like you have the guage hooked up right, did you make sure the line isn't kinked anywhere?

I ran brand new line, and no theres no kinks in it. I think i found a problem though, I think the orings on the pressure chamber are shot, i have wet seepage around both of those, and that would cause a drop in boost and an incorrect reading. I'll check that sometime this week. Thanks for the help guys!

how are you checking for boost? Just in your driveway reving it up or are you actually driving it? You try putting a little weight behind it(trailer) and see if it shows boost?

Driving up a hill with your throttle on the floor is when you look for boost numbers.

Just reving it up sitting still, probably never make the gauge move.

You need RPM's and hot exhaust from working the engine to make good boost numbers.

That and the IDI turbos don't scream like they do on the newer trucks.

The high base IDI compression ratio will not let you run boost pressures like the Stroke and Cummins motors do.

Then I will have to try under load. I didn't think of that. I was definately reving it in the driveway looking for boost. that explains alot. I am going to replace the two orings on the pressure chamber, then I'll try again. Thanks again!

With my not stock engine, I can see 2 PSI reving the engine.

That is the most I have ever seen a turbo make sitting still.

Take it out on the highway, 20 PSI is easy to get.
