Boost failure

Hey just wondering next steps I would take to solve this issue,

Was out lastnight doing some brake boosts in super sport mode with stage 3 ACN Cobb tube (2013 Ralliart)

When driving home lost all boost, pulled a code P2263 waited till morning to Check found the middle joint on stock turbo piping between turbo inlet and air intake has come apart so I fixed and tested no boost still, but new codes p0068 and u0167

Cobb access point reads 25+/- 2psi on WOT
Cobb access point reads - 11 / - 12psi on high rpm throttle release

EBC solenoid is stock and original, boost pill has been removed, larger intercooler and mushroom air intake.

EDIT this is normal running numbers

Cobb access point reads 25+/- 2psi on WOT
Cobb access point reads - 11 / - 12psi on high rpm throttle release

after the whole pipe burst im doing maybe 1psi -5psi from first to sixth gear

So the joint between the MAF and turbo came apart?

seems weird

check for a physical boost leak post turbo, BOV stuck open etc
