2014 Ram 6.7 Cummins. I had the turbo and actuator replaced in November 2018. In January 2019 I did a full delete on the truck and had it tuned with EFI Live. Now the exhaust brake sticks open even when the button on the dash is not on. When the button is on then it sticks even more! I have zero throttle when it does this. Replace the actuator again in February. The truck is doing everything that it is calling for. HELP!!
