no boost

[stovepipe]

I have an 99 dually 2 wheel drive that I can not get any boost out of it at all, can some one give me some ideas to look at or look for. Thanks JR

By saying you have no boost I take it you mean just very little?

Check for leaks first, boots and gaskets mainly. The intake gasket is a known culprit for this if you never check torque on the bolts. That long plate under the injector lines? That is the intake cover. Easiest way to check is by making a plug for one of the boots and pressurizing the system.
