The car didn’t start at all a couple weeks ago then the tuner came down and adjusted the tune.
Now, the car gets CEL flashing maybe once every 3-4 times I drive it with NO power at all when flooring it. The tuner said its a safety parameter they put in place. My oil gauge has stopped working, my 3 other maps the tuner gave me are gone. Heavy rattling sound from the undercarriage (maybe exhaust?).
I have told the shop about all these concerns but haven’t heard back just yet.
The car is meant to go back to their shop this month because they didn’t know about the subaru belt tightener pulley which I supplied with the kit, so they’re going to install it for me.
I went with supercharger because it’s my daily and i wanted a “hassle free” build. But this has given me issues after issues even after I got my car back. Very unfortunate.

I haven't really followed this thread but reading back it sounds like the shop definitely don't quite know what they're doing. I strongly suggest going somewhere else.
As described in one of your previous posts boost falling off before redline is 100% a direct symptom of belt slip. Since you already have an RPM belt on the supercharger side that is most likely not the issue unless it's extremely loose (try pressing on the belt with a finger, it should be pretty stiff with little to no movement). Looking back at your pictures your serp belt is way too long without that extra tensioner, I run that K071045 belt WITH the tensioner to take up the excess slack, and even then I've been recommended to run the K071040 belt instead which is half an inch shorter.
If you sort out the belt situation and it's still a problem, then it's the intake.
Also, what happened to your engine grounds? Were they relocated or did they simply delete them? They are usually attached on the frame near the supercharger and attached at the top of the engine where the supercharger bracket brace is.
