997 turbo boost issues ( maybe )

[Fat Porker]

While I'm here can I ask your guys opinions on exhaust swap and whether decat would be too loud or doesn't it work that way with these cars

I have a 997 turbo gen 1
The issue I have is low boost only 0.3-0.4 maximum upon checking electronic actuator rods for sticking/seized it revealed bank 1 cylinder 1-3 was moving freely also bank 2 cylinder 4-6 also moving freely both by hand only.
But upon switch on and off of ignition only bank 2 cylinder 4-6 would do the full sweep movement of rod as it is supposed to do. Bank 1 cylinder 1-3 no movement at all of actuator rod as is supposed to happen when switching ignition on and off. But full movement of both actuator rods when moved manually by hand so neither seized. This makes me assume that the electronic actuator itself must be broken ?? ?? Be grateful for any advice on this. Thank you.

Rule out a physical leak from the system now you know the actuator rods aren’t stuck or disconnected.
