so i am looking for someone in az to advance my timing do my valves and put a new governor spring in the truck, i called around in the phoenix area and found a2z deisil in phoenix. i forgot the name of the guy who i talked to but he said that putting a plate in is the worst thing that you could do because it messes your pump up some how. he said he is a member of the tdr website but said he could get the same power without doing a new plate and all that im doing is wearing out my pump and it wil be gone in a year so my ? is has this happend to anyone or is he full of it? he said he has been a cummins mechanic for 12 years just was wondering what you guys think.
