if there is any way to fix this let me know because my truck needs power for hauling heavy loads

Do you notice the tell tale noise of the hiss out the tailpipe while this is going on? You can unplug the electrical connection on the turbo pedestal so the valve will no longer be activated. Its a two wire plug with a wire clip unplug it while the truck is off and see if it cures your power loss while warming up the engine.

Here is a pick of my pedestal when I had it out of the truck. If you look on the front you can see the solenoid with the female electrical connection. That is what you are looking for to unplug
