dont buy anything, I work for international as a Tech and deal with this stuff all the time.
But when you throw over 22-24 pounds of boost your check engine light will come on but shut off after some driving to make sure it doesnt overboost again.
also if you shut your truck off and turn it back on the light will be off.
So Since when your light comes on when under hard acceleration and more when under a load thats when your turbo is going to make the most pressure
I throw that code all the time because I get up to 35 pounds of boost when im towing or really mash my pedal
The ICP higher/lower than desired comes on because the computer sees the high boost and the the ICP an IPR pressures are not proportional with what the boost should normally be. Hopefully that made sense
