LMAO, yes it's worth doing it. The DPF is the absolute killer of power, and you'll get a MPG or 2 out of it. However, the best bet to increase your MPGs is to install a propane injection system. you'd be looking around the 30-35MPH range with a propane system, and propane is dirt cheap compared to diesel, not to mention the gains in power as well :smileup:
