    I was wondering if u found the issue with ur truck. I just did the delete and changed out turbo. Now I have same problem. Surging and hiccup when at full throttle. I'm pretty sure egr valve is staying closed.

    Was your delete done properly? If ECM was not removed from truck for that very labor intensive process then it was not done properly.

    It is behind the instrument cluster. It will be zip tied in there either along the main harness or the steel cross bar. It has a four wire connector going to it, it is black in colour. The battery is replaceable.

    IV been to the dealer school for this ( ex dealership mechanic) and I would say it's either programming or a surge in air from egr components. Assuming the egr is still on the truck .

    Once you get the whistle noise, check for boost leaks. If no leaks, you probably have the high pressure turbo failing. The whistling is caused from the turbo shaft moving laterally excessively.

    The books don't directly say, but I would assume if the code is active then some sort of derate will happen.
