No boost at highway speed
Just had my egr cooler and oil cooler replaced as well as a coolant flush done at the local ford dealership. This took care of all the white smoke and overheating problems i was having. Went to take the truck on a road trip today and upon acceleration boost guage went up as usual but once i set the criuse control at 70 mph boost guage dropped to zero and stayed there until i went up a hill. The truck also felt like it was missing every once in a while. Anyone ever have this same problem or know what this could be caused by.
