I won't scan the Diesel Power article, cause it was way to hard to make the other one small enough to fit. It's the Aug. '11 Issue. The article is no really detailed and they don't seem to make a statement of exact reduction in fuel use. However there graphs clearly show a reduction in fuel use. Like most lab tests, I presume they are showing the best results, so your results may varry. In their advertisements, Snow claims a 6-12% economy gain from their MPG Max system.
You really need to call TS and see if they can get you a tuner that can also deal with your EGR.
You drive your rig well, it has a big head start on the aero front, so I gotta believe there is a good bit to be gained from tuning because your mpg ought to be better than what it is. You should open up a fuel log for this so we can keep track as you rack up the miles.
I'd really like to see what improvements could be made aerodynamic wise. Be nice to see some wheel covers, skirts and close the gap between the cab and trailer.
