I have the flow master outlaw kit on my 2016 M6 challenger. I have followed the video and my car is still throwing codes like it’s not recognizing the fake valves. How do I check my actuators and see if they are good or not? I am thinking I have a bad valve. When I unplug them they make a noise when I plug them back in but I dont see they are moving.
Just wait for exhaust to get cold with valves open and wire the valve open all he time with wire. Put them back and take wire off if you decide you want them back stock again. Works well.
