Sounds like you must have a boost leak somewhere as you should definitely have enough fuel to get more than 30# of boost. I know that on my '02 I can peg my 35# boost gauge easily, with less fueling than you have.
Have you pressure tested the system for leaks?

how do you pressure check??

sounds like a boost leak, my 200's and drag comp would make 40lbs all day long.

get a spray bottle of soapy water, crank the truck up, spray all your boots, intercooler, ext. look for bubbles

thanks ill try the bottle will my boost be high enough to see bubbles holding still an free reving??

at idle it should make enough pressure to see bubbles

You can fab up a plug for the intercooler boot turbo side using PVC pipe. If you have shop air, pressurize the system to say 40PSI and then do the bubble check, as well as letting it sit to see how fast the system loses pressure. My guess would be either intercooler boots, or even more likely a slow leak from the intercooler. I can assure you it doesn't take much of a leak at all to prevent boost from increasing...

Here is what i did to pressure test my intake system

This is the Setup i used it is a piece of 4" pvc pipe and cap with a 1/4pipe valve stem i just drilled and tapped into the 4" pvc cap and a pressure gauge 1/4 pipe as well the gauge is so that i can pressureize the system and monitor the pressure.

I attached the setup to the air filter tube just so i could test the complete system and i know that i am not getting any thing pre turbo either dust dirt ect. Also in this pic you can see the boot is "deflated" you want to make sure that the clamp around the tester setup is very tight because at just 15-20psi if the tester pops off it is very leathal. Dont ask me how i found this out
02 Dodge 062.jpg

In this pic you can see the boot with pressure its only at about 15psi but definatly blows up like a balloon so like i said make sure that everything on the tester is tight. Then take a spray bottle of soapy water and spray around all of the intake system boots from turbo all the way around to the intake horn and around the heater grid have heard of the gaskets for the grid leaking as well. I only pressurized my system to 25psi but at only 10psi the leak I had showed up at the boot that connects the IC pipe to the intake horn so any leaks that you have should show up at about 25psi or so.

Like I said used caution when pressurizing the system and start out slow, got in increments like start at 10psi then 15 and so on just so you are not blowing boots out or the tester flying off.

thanks guys im goin to build me a set up. an see if i get to the bottom of this leak

---AutoMerged DoublePost---

update well i built a tester an found a big leak in the intake plate. I replaced the intake gasket whith a metal one took the truck for a ride still only pusshin 30 lb so im goin to do a nother test to see if i have another leak this is puzzling the leak on the intake plate was so bad i couldent get the pressure gauge to even reach 5lb

With a big leak like that you may find that you have more leaking around the boots as well let us know what you find.
