OK, Ive got a code P0480 Cooling Fan 1 Control Circuit/Open (Low Speed Fan Relay) This is the second time I've this and the last time they replaced the Centrifical clutch on the fan. I'm not sure if they cleared the codes either.
Yes I do have a Banks Six Gun installed and have noticed that every blue moon the truck will hiccup right after startup. I also have noticed that once or twice during relativley cool weather (around 47 degrees) the cooling fan kicks in hard, which really makes no since.

I Plan on contacting Banks on Monday. I currently have th module removed and I'm going to the shop on Wedensday for them to look at it for other things.

Does anyone have any sugestions as far as the root of the problem if there really is one
