Hello
to get that fault then there's something wrong with the turbocharger
I'd first check all the high pressure hoses post turbo/s for any split hoses or cracked metal pipes, also check the ends of the intercooler as its not unheard of to pop the end caps off under high boost.
If this is OK then remove the high pressure intake hose after the turbo and have a feel of the turbine wheel - there should be no play radially at all - but a little bit of axial / end to end float is normal
and if thats OK then they are prone to issues with the wastegate actuator
this image shows inside the actuator and you can see the solder joints that are burned
if this is the case they can sometimes be repaired by re-soldering
hello
OK if the turbo actuators are new with the turbo then check the high pressure hoes next and I'd also remove the hose to the engine so you can see the throttle and then with the ignition on and engine off have your assistant push down on the throttle whilst you look at it to ensure its opening fully
