While propane in moderate use will increse power and fuel economy it's just not a good thing. The reason being is it's an uncontrolled burn. The propane is burning in the cylender before the piston gets to TDC putting added stress on your pistons, rods, main bearing, rod bearning, and crank. In moderation it's not enough extra stress to dammage parts right away but over time it can. Not to mention the huge urge to keep tweeking it up little by little to get more power until something does go pop.
The reason it is an uncontrolled burn is because it is injected into the intake stream and is in the cylender before it starts compressing the air. Once the compression gets high enough to build enough heat to ignite the propane the propane will start burning. This will be before the injection event starts and there is no way to accurately start the propane burning. Idealy the diesel being injected and burning will ignite the propane but that's just not what is happening. Propane has a lower flash point than diesel much like gas so it will start burning before the piston reaches it's full upward travel.
