Cleaned Henry up yesterday and took him to a car show about a mile from the house, I was the only Diesel there! Henry was looking good and as I left a did a big smokey burn out which isn't like me but the car show was at my old high school, I was reliving the old days! Then I started having boost leakage under high boost pressure see Boost leak thread in the 7.3 tech section. The new exhaust is good, the only time I really notice it is when I am pulling the trailer.
