well guys with my set up listed below i am only seeing 29lbs of boost, to me that sounds kind of on the low side. Just wondering how i go about checking/fixing boost leaks. And help would be greatly appreciated.
 
sounds normal for stock injectors... on my dads 00 it runs 22psi with stock injectors and 36psi with 100HP jammers

You should definitely be able to get more than 29lbs of boost with your setup. What kind of EGT's are you seeing? The most common place for boost leaks is the intercooler boots or the intercooler itself.
You can pressurize the system to check for leaks. I don't have a write-up handy but you can rig a setup using PVC tubing. If I can find the write-up I will post a link.

If you want to buy a boost leak detector, there is always this option:

Otherwise I found this pic from member Homestead over on DTR:

Hope this helps

I kind of doubt you have a boost leak then, or at least nothing serious enough yet. When I had a boost leak the truck was pouring black smoke and EGT's were through the roof (I had lost an intercooler boot though). It probably is worth checking out if you get the chance, just to be safe.

Are you sure your wiretap is good for the Juice? That would explain the lack of boost if you're not getting as much fuel. It may be a long shot, but it's all I can come up with at the moment.

I think 29psi is not bad with stock injectors and just Edge Juice. Add a set of 125-150hp injectors and you'll see 40psi no problem.
 
When I bought my truck the intake gasket had a nice chunk missing out of it. I would check your wire tap too.
