Hello, new to the site. 2013-2500-6.7L....Question for you gentlemen. Shop says actuator is bad and I'll need a new turbo. From my own research I feel I only need an actuator. Builds plenty of boost just no engine brake and a check engine light is on. $3,865 for a reman from the shop I took it to and I've found them cheaper on line. Whats your thoughts on this please?? Replace turbo or fix actuator?
