mfaley; I just can'y contain myself any longer, the answer to your problem is to go out and get a POWERSTROKE! [img]/forums/images/icons/blush.gif[/img] [img]/forums/images/icons/smirk.gif[/img] That's only my opinion. Like cowboydoc saying, the programmers that Superchips put out work great. Myself, like him, run on the low setting. I don't have a pyrometer either. Next stroker I get I will though. Just joking about the Stroker though, that little Cummins may just actually be a better engine than the Navstar. But I think that you get a lot of bang for the buck with a good programmer. Also changing out to a less restrictive exhaust would help to keep the egt's down, let alone sound really bad. Some guys around here leave the stock pipes on, and get rid of the muffler. Doesn't really produce an unpleasant sound like one might expect, and the turbo spins up quicker, giving you a little more seat of the pants fun. [img]/forums/images/icons/grin.gif[/img]
