Once again, Quintin is right on the money. 
Original plugs were replaced with PZT-1F-F4 plugs under TSB 05-10-15. They also did a reflash under TSB 05-10-02. All I know is that the idle quality is better, and there is a noticible improvement in the low end. Feels like they woke the big pig up.

My truck was built Mid March, 2004. Could I approach my dealer with these TSB's and get new plugs.
My truck hase developed lately a rough startup idle. The truck will sit for a day or two and when I start it up on a stone cold motor, its a rough idle..
I guess it's always been there, just seems to have gotten worse.
I got alot of mods on my truck so I really need to know what to say/do if I go to the dealer and tell them about it. Only way I could replicate it to them would be to leave it there over night.. Dont really want to do that.
Thanks
