please help!! first diesel.
 

Hey, I have an 08 f250, im experiencing a loss of power, feels like im not getting full affect of turbo, and sounds like an air leak in behind the turbo, can see black soot. This morning on my way to work the truck ran alright leaving the house still with this problem tho, 30 minutes later when I got to town my turbo wouldnt spool at all, put my foot to floor and the turbo gauge just creeped up total loss of power. Its about -25. Degrees Celsius
