Boost detector issues

At the risk of looking like an idiot, I cannot for the life of me figure out why my boost detector will not build more than 1lb of pressure? I hear the air escaping from the passenger side exhaust manifold/up pipe joint area. How is the air getting to the hot side of the system? Could it be a wastegate issue? Am I overlooking something simple? Thanks for the help!

Crankcase? It's not in the picture but it looks like you still have the CCV hooked up.

I'm just tossing some things out....

It could be your Wastegate. Have you inspected it?

I assume your being supplied with Shop Air of 90-100 psig and regulated down to 15-20 psig? It requires quit a bit in reserve to maintain flow.

You're using paired fittings on the Cap and Air Line?

You could have a blockage in the fitting itself on the Cap.

It could also just be a leak at a couple of your CAC Boots or perhaps the CAC itself.

I would suggest just looking around real good beginning on the intake side (which hardly ever leak - but you never know).

Sorry I couldn't be of any more help.

No. Pretty common oversight.
