After 5 years and 80k miles, I'm seeing the actual manifold pressure lag a bit more behind the requested pressure than it used to. I'm watching the ratio actual/requested, and it drops a bit longer below 1 when stepping on it, and stays for a bit longer above 1 than it used to when taking the foot of the pedal.
I'm suspecting some crud accumulation on the adjustable turbo vanes.
What's the recommended way to clean them, without obliterating the DPF while doing it?

- Water mist into the intake?
- Can one flush the turbo while in place (disconnecting exhaust side inlet and outlet)?
- Complete removal necessary?
- Has anybody done that him/herself, or had it done at a car shop? How much?
