Customer: "after the exhaust shop did the exhaust they tuned the pump. Well it went like a rocket no doubt. After a few months though I'm starting to get worried by the every increasing soot pouring out of the exhaust. In fact when we last towed the van she got quite hot going up a big hill.... "
Now the customer is in with us and what do we see. The usual. Fuel screw wound up, black smoke and injectors BLUE from combustion heat and inconsistent spray pattern across the 6 of them.
