    i own a 97 chevy dump 3500 6.5 D with 49k, 4x4., etc. it recently was in the shop with a check engine light. the truck seemed to hold back when accelerating then it seemed like a valve opened up? then it ran fine. the code read turbo boost selenoid which was replaced. it has done it since once but still doesnt feel the same.

    PMD? Have you replaced and relocated your PMD? www.dieselplace.com has a huge 6.5L section over there.

    It's the brains of the Injection Pump, telling it when to fire fuel into the cyclinders.

    This is from dieselplace.com there write up is the best I can find and I don't have that amount of time.
