A standard kit should knock your EGT's down at least 200 + degrees with no problem. On a stock truck duramax it normaly sees a 250+ temp drop. When you chip it, and and more boost you tend to need that second nozzle. A M14 teamed up with a M5 or M7 work very well for this.

Progressive is best for daily driving on TD's so You not sucking down your tank as rapidly.
