After my truck was in the stereo shop for a couple of months...it has no power! Boost is way over boost 30+ psi on physical gauge and the edge insight. Good thing I have headstuds, but at this rate...
Pretty sure I got stuck vanes or a dirty turbo...how much does it cost to have them cleaned normally? I don't have the time and I don't wanna get cheesed!
Any idea what you may have paid for such service?
If it is unrepairable, what do you guys recommend...upgrade?
What is your MAP, BARO and EBP reading at KOEO? All should be within .5 PSI of one another. Have you cleaned the MAP hose and nipple, the MAP sensor is located on the passenger side just above the evaporator housing and is connected to the passenger side of the intake manifold via a rubber hose, pull the hose and blow compressed air through it to be sure it is clear and make sure the brass nipple that it connects to on the intake manifold is clear, next pull the EBP sensor, depending on the year it will be mounted on either the thermostat housing ( 03-04 ) or just below the FICM ( 05-07 ) and attached to the front of the drivers side exhaust manifold via a steel tube, remove the sensor and take a piece of weed whacker line and run it down through the metal tube to ensure it is clear. And also what year is your truck? Disregard the last question, I just read your signature.
If your truck sat for 2 months not being driven at all the vanes inside the turbo may have seized up from rust, the good thing is they can be removed and cleaned.
+1 on what mustang309 said about how to verify.
I think it would be somewhere around $300 if nothing's broken or badly pitted. Many go with the Powermax for replacement (it's a little cheaper) but usually just a clean-up works fine.
Here's a video of the job if you're interested.

Would removing the inlet pipe on the turbo and spraying the WD40 into the opening with the engine running do the same thing? less the never seize of course..... Sorry I couldn't help myself, I do find myself wishing there were an easier way to get to the cleaning part though.
The guide vanes that "freeze up and stick" are in the flow path of exhaust gas to the turbine impellor (not the inlet air compressor impellor). They direct the exhaust gas flow so that the turbine section will either produce more or less "work".

Nope, the vanes are on the exhaust side. Unfortunately there is no quick fix besides taking it apart.

Yeah, I was only funnin you with that smart alec question, lol. I will ask you how often these usually have to be cleaned ( if there is really any way of knowing) or is it all over the place depending on driving habits and such.

It really depends on your driving habits. If the truck sits for long periods you'll have sticky vanes. If it works often then you may never have a problem. IMHO it's the people who use them for daily drivers and try to get max mileage that have the most problems. I, personally, have never had a problem (knock on wood) with sticky turbo vanes, but I don't *****foot around either.
I think this is a related question. Does fuel additive, like Diesel Kleen, benefit the exhaust side of the turbo. i had thought it helped, but not sure.
I called my local shop and they quoted me $400 to clean it...I havent had a chance to do my own trouble shooting, but I wil sheck those parameters tomorrow morning as I drive there and I'll let you know what I find and what they find!

I'm going to clean a powermax on Sunday that gets fuel additives in every tank, is driven fairly hard, and tows on a fairly regular basis but it can sit for extended periods in the summer. It's experiencing intermittent symptoms of sticky vanes: over boost, black smoke, blowing hot side CAC at turbo. In my mind this turbo should be virtually "spotless" inside but yet it sticks. I'll see what it's problem is and try to get some pic's when I get it open.
