You may have left a vacuum line disconnected, or inadvertently knocked one lose. Tapout talks about this happening after people change plugs:

Here's a link to the page. The info is at the bottom:

Note: Did you recently replace your spark plugs and now only have 7 to 12 psi of boost? Every day we hear from people who change their spark plugs and then only have 7 to 12 psi of boost. Most of the time there’s a simple solution to this problem. Pop the hood, let the […]

Ya this is common apparently. I wish I would have seen you link the other day Feezy. I knew I saw that info somewhere but was damned If I could find it. For me I was angry because I'm not a wrencher and took it in to a tuning shop to hopefully not have any issue but they forgot it too. Thus I actually opend my own hood and fixed it... lol.

Jdee if you have done it already great if not the two common spots are right near each other the one you can see right from the top the other is almost underneath the first and you do have to remove the cover to see it. Just FYI

I was able to get it hooked up, missed the one in the rear on the left side.

I’ve dealt with enough boost leak issues to know not to get worked up

9/10 when it’s now working the way it should it’s going to be a minor detail that’s easily overlooked

How difficult is spark plug changes on the 4bw? I know the hellcat is a pia and hoping to do these myself.

the scariest part for me was removing all the lines connected to the solenoids and once I did it was very obvious how to put it back together.

Should be a simple task for someone that has the right tools.
