    Hey guys, I have a 2000 C12 that has started surging/bucking really bad at times right in between about 10 and 20 lbs of boost. I have new fuel filters and air filter and run quality fuel. Any ideas??

    I would recommend checking your primary fuel pressure ... it sounds like it may be unstable when you are using quite a bit of fuel ... also check for air in fuel .. are you having any problems with start ups... if all that checks out check the camshaft and crankshaft position sensors ... these can cause a number of speratic power problems ...
