Boost leak maybe.
Bring it over and I’ll inlet pressure test it.
In the meantime do a visual inspection, also check the FPR is still hooked up to the nipple at the base of cyl4 inlet manifold runner.

As you can see, it’s a stored code, but you have major fuel corrections currently and a little low load knock.
Intriguingly the IAM is still at 1.0, which suggests its kinda coping ok, off boost at least.
I wouldn’t be using any boost atm till you get it sorted.
What rpm is warm idle?
When was the ecu last reset?

#ynansb = you need a new short block lol.
Hopefully you got the Btssm kit in time.
How’s the driving experience been recently, compared to when you got the car?
Are there any driving symptoms apart from eg excessively rich exhaust?
