I got one from the local Navistar truck dealer
The closest for me would be about 70 miles away.
Do you still have yours? Care to share?
Also, is there anything else that I need to check for that could be aiding in the surging beside the turbo?
How about the ICP (what does this stand for?) (did some searching and saw where this could be a reason too)
Any other sensors I should check/replace?
