I had this issue as a result of a loose wastegate.
There are a host of different things that could cause it though. Primary concern it to check for boost leaks.

I'll check them. Just went over every elbow/hose and clamp connection from hot side turbo to IC to charge pipe. No holes, cuts, or loose clamps. BOV is good. Charge Pipe is good. TMAP is good. Throttle body has a new gasket torqued to 8nm. Intake manifold and PI rail have new gaskets torqued to 15nm.

The target is 23psi and you are making 18psi at one point. That is the reason for the code. I would smoke test 1st. Which you can make your own for like 40 bucks.

If there was a leak wgdc would be really high, this looks to be more of a tune issue. I would increase wgdc in the areas you're below target if you're familiar with tuning. If not talk to your tuner or learn to tune yourself, although the latter is not for everybody.

What turbos/mods do you have?

I have a custom tune via MHD. Recently downloaded TunerPro to install the Reflex controller. I've updated my custom .bin file once with some suggested edits from the o2 catalyst thread. Which means I have no tuna experience. I have installed all of the mods/maintenance items on the car. DCI, Charge Pipe/BOV, 7.5 race, Inlets, DPs, Index 12, B58 coils, plugs, BPM4, Stg2 pump, Radium FPD/Filter, PI 750cc, Reflex, FF sensor, Vac lines, boost solenoids, 3.5 TMAP, 2xCatch Can, Imp racing oil cooler/thermostat, Imp racing trans cooler, stock turbskis.

Maybe in here some where?
