The old BRV's were fine, I went to lubricate the VTG actuator. rods and found the passenger side disconnected and laying against the exhaust. figured that was my issue however the symptoms got worse.
The issue is with boost loss at the top end under hard acceleration will need to to a full leak test next. Builds normally until 4,000 then drops out almost like a loose hose or bad seal is intermittently losing its contact or seal.
On the freeway I can gradually feed power in in 3rd,4th,5th or 6th and boost gets up to 12PSI.

Boost leak test completed found one small leak behind the oil filter housing any thoughts on how long pressure should be held? dropping (1) PSI every 12 seconds. no other hissing noises.
