Turbo underboost code Po299
Hey guys. My service engine soon light came on last Sunday, lastnight I went and got the code pulled and it came up PO299 Turbo/supercharger underboost. I am not noticing a difference in power and the gauge hasnt changed. I bought the truck from my girlfriends dad when he got his 2011 6.7L. He always drove the truck pretty aggressively also pushing the throttle as far as he could. I dont drive it like that at all. Im really nice to and just let it crawl up through the the gears and rpms and dont use the turbo all that much. Not like he did anyways. Im wondering if maybe my driving style has cause this. Is there a chance the turbo could be dirty, gummy, or plugged up in anyway since it doesnt see alot of hard use? Im new to the diesel world so please bare with me, I have done all the searching I could. I have also checked all hoses and tubes for loose connections? If I change my driving style is there anyway I might be able to clean the turbo out that way?
