I saw an episode on "Trucks" about a year ago... before I even had a diesel, and the host put a propane system on a new diesel truck. He dyno'd it before and after and the system was a bullydog system I think. fairly simple to install, the results were much more hp. and actually the propane had some additional benefits which were a cleaner burn... and the engine ran MUCH cooler. I thought this was very odd. In anycase it was awhile back but I just remember being impressed. sounded like a no loose senario IMO.
