2003 F-350 7.3 diesel 240,000 miles, with Banks Autominder programmer set on economy and weak wastegate actuator made small pop noise from under hood, lost boost and had some black smoke-does this indicate failed wastegate actuator
JA: Many things can cause a car to make those weird sounds. Some simple, some complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Ok
JA: Great! What have you tried so far?
Customer: Physically moving wastegate actuator rod, other than that nothing as it just happened today during heavy acceleration while getting on freeway, was not towing anything , had newly installed Banks Autominder programmer set on economy,vehicle has NO other modifications
JA: Is there anything else the Ford Mechanic should be aware of about your Ford?
Customer: No, except truck has never towed anything

Hello, so the vehicle is losing power and blowing smoke? What color smoke is out of exhaust?
Customer: replied 1 year ago.
Black at first and then only on downshift on highway while trying to go up a hill at 60mph, I pulled over and used the Banks
Autominder programmer set remove the economy setting and reset to Stock settings,black smoke stopped,but still no power, could get 70 mph on flat highway but would not maintain speed up small hills on highway
