    Question Waste Gate Check

    What is the proper way to check the waste gate actuator? I moved the rod to the read and pumped up the diaphragm. It started to move slowly and by about 3 inches it had moved all the way forward. The book said it should move quickly. I then pumped it up to 15 inches and it bled down to 3 fairly quick. If I pushed the rod back then the pressure raised back up to over 5.

    Is this good or bad? I am blowing black smoke on acceleration. The harder I accelerate the more smoke I blow. The injectors are new with less than 4K miles, new heads, and she seems to run pretty good, but I am only getting 12 miles to the gallon
