Well, I took the first step today and pulled the plug.It took longer to warm up as expected so I turned on the engine brake and engaged the high idle ( ambient temp 60*). Engine light came on rite at start up. (code,egr voltage low)Ran the same other than my millage went up an easy 3mpg.Being rather curious, I removed the MAP sensor that sits right on top of the air horn next to the egr and it was covers with soot, about the thickness of 3 sheets of note book paper. Not having ant cleaner I just gently wiped it off and reinstalled it.Ho ya millage, 2353miso what is next find some RxR tracks and see if the dpf will fall off?Where do I get the plugs to build my foolers with?

You could try Caspers Electronics that is where I order my plugs for the high idle kit I built... http://www.casperselectronics.com/store2/

or, you can get a Smarty or XRT that comes w/ sims and a delete pipe....plus gives ya some power....what year is your truck?

I think I'm going to go with the sims.That way if they want to mess with voiding part of the warranty they will have a harder time doing it.I hope?
