Turbo underboost P0299

I had my truck checked for codes (not by the dealer) and DTC code P0299 showed up. The code is for turbo underboost, could be due to a dirty turbo and the vanes are sticking or one that needs replaced completely.

How can I get them to replace it?
Unfortunately the code was erased and I'm trying to get it to act up, any suggestions?

I know this is a pretty common problem, and some dealers just throw a new turbo in the truck. I'd prefer a new one over a cleaned up, worn turbo.
Any ideas?

definitly stuck turbo , depending on the dealer how they handle it , what weve been told by ford hotline , if the turbo is just coked up , clean it and
reinstall, if turbo is coked up more than likely the egr will be pretty dirty also and probably best to clean both , if turbo is at all rusty , needs to be replaced , like i said different dealers handle it different ways and also techs handle it different ways , me personally , it depends on what the turbo looks like once i get it off then i make the call from there, you may ask to talk to the tech and tell him your preference , it does make a difference to how i handle it depending on the customer sometimes

Is there a type of driving that would make it more prone to tripping the code?

I had this code and the overboost. It was rusty so they replaced the turbo.

I have been having the same code pop up. My truck is an 05 with 25k miles on it, and I have had the turbo replaced at 17k miles due to stuck vanes. I am now having problems with the vanes sticking on the turbo again. I installed a Banks Powerpda at about 20k miles and now I will have to remove it to have a new turbo installed. You would think Ford would do something about this problem. The service manager at my Dealership told me I was one of only 3 cases he knew of having a seized turbo. I am so disgusted with the reliablity of my truck I am about ready to give it up!

Do you drive your truck gently?

I drove my truck somewhat gently while it still had the first turbo. Mainly because I didn't want to beat on my brand new truck. After the turbo was replaced I started driving it harder and harder. Now with the help of my Banks tuner, it is driven plenty hard, however I do let it sit for a couple days to a week at a time without driving it. (College Lifestyle) It will still spool normally most of the time, but after getting into it, the turbo will get very unresponsive until it gets an extreme load on it, then it will boost to as much as 34 lbs. I have been trying to keep it cleaned out (driving like I stole it) with no luck. Hopefully the next turbo will last longer. The first one was 17k miles, now 8500 miles, whats next 4250? Then 2125? If so I can promise you this truck will be living somewhere else.
