temporary boost loss...
two different occasions i have noticed a loss of boost.
one time I was pulling an empty 18foot enclosed trailer
the other time I had a Dump trailer loaded to around 16000lbs
both times i was pushing 75 mph and it almost felt like it dropped into a double overdrive Rpms were like 1.5-2k... boost dropped to zero pedal went to the floor, stayed zero boost for like a quarter mile and then shot back to about 20+ lbs where it was before the incident. cant duplicate it empty, fuel mileage has been less then usual but probably unrelated
I have no guesses and im praying its a cheap easy fix.
