Your computer is giving more diesel for more power. You might check to see if someone has put a different chip in. If so nothing wrong the computer is just giving you more fuel for more power. Within reason now, if your blocking traffic with your smoke you have a problem.....

tcarda, thats where you're wrong on the smoking. my 94 smokes very little and thats when i haven't been running it down the hiway in a while. pulling a pretty long hill out of Ft. Pierre, it doesn't smoke at all and thats a 1 1/2 mile long hill. all the way to the floor. if it's a 94 or newer 6.5 turbo, it has a pmd to control the injection. keeps it from smoking. if the vacume pump isn't strong enough, the waste gate doesn't work right, also if the dashpot for the waste gate isn't working right, it either won't open all the way or it opens too soon. opening to soon will make it smoke really bad when you put it to the wood. but your right on the power, it doesn't have a lot of power, but if the load isn't too heavy,like mine, it will get better fuel mileage than the others from that era.

I took the vacume lines off the boost senser loup them to gather BOOM no more black smoke 15 + on the boost. defueling up hills or tall bridges
if thay takes care of your black smoke put some springs to hold the wastgate closed
