Alright guys my fire department has a brand new 2006 ford f 350 with the powerstroke diesel in it. It has 2190 miles on it. It has had the turbo replaced on it twice. The check engine light has come on and the pulled the code which is p0299 which is underboosting. THe truck isn't run very much. It is usually just pulled out side and run for about ten mins then put back inside or if its lucky is gets to go on a brush fire. I don't understand why this is happening can any one give me any ideas or what we should do with the truck.
