| does your truck still run strong after getting the overboost code? If it does, it is probably just your programmer causing it. Some cause it and some don't. What is happening is the computer is seeing a higher boost at a lower throttle position. I have thrown the code a couple of times with my truck with no other problems. I don't think your truck has an EGR on it...IIRC 03 and newer california emissions came with that stuff on there.
