Since this is on JB4, I assume you can record a log. I would start there. If not, display the gauges and set one for Boost Target and one for Boost (Boost Actual) and see how much you are underboosting. My guess is boost leak

Have you checked the couplers going from the turbos to the intercoolers. I’ve heard their notorious for cracking and go bad.

Codes 6 months old ?

What year is car and what maintenance that could be a lot of things but common things are the vanos solenoids and like already said first thing to check before throwing money is leak but I would assume you would know if was leaking . How much boost are you running ?
