You might have a turbo sticking thing or faulty sensor somewhere.
possibility, leakage on the intake/exhaust/EGR system.

- check ICP and connector
- check Turbo solenoid and connector
- check oil pressure

if none of those applied. check your intake and turbo.
remove the air filter inlet and intake pipe from the turbo. visually look for any play on the turbo shaft and oil leak.

That is just in case if it is a faulty turbo you dont want to have a runaway engine.

If everything is seem to be normal to you.
Then you just need to drive it hard like a stolen vehicle. * prefer to go do it offroad*
to blow out those sticky carbon off your VGT turbo.
