Low Power, Fuel Mileage Drop - Help Please

Low Power, Fuel Mileage Drop - Help Please
I have a 92 Dodge D250 with no modifications other than an Air Dog Fuel Pump and all of a sudden I have no power and fuel mileage went from 19-20 miles to the gallon to 8 miles to the gallon.....I have to put the pedal to the floor just to get up a slight incline. Does this sound like a Turbocharger? Not sure what would effect me so dramatically like this..
If it is a Turbo and I need to change, any recommendations for replacement? Can I troubleshoot myself?

No turn connectors, don't know about a boost leak but is the turbo is no working at all that would be the same? Don't know what a "EGT" is but I was on a trip back to my home and had to drive 8 hours straight in this condition...couldn't get over 65 miles an hour on the level, about 55 mph on a grade blowing black smoke the whole time...

EGT=exhaust gas temperature, I agree on a possible boost leak. Look all the rubber boots over real good and check to make sure none look as if they have moved on the piping I"ve seen the clamps fail. If there are no obvious leaks do an either check. Why do you suspect the turbo, is it making extra noise or some squealing sound which could also be a boost leak? Most turbo failures on stockish engines are oil leaks and not complete turbo failure. Rocky

Boost
Checked all of the boots (at Turbo, both sides of Radiator and at the intake).
Basically my theory that the turbo might be bad seemed to be false so I have no idea what to check next.
