So many opinions..........so little facts to base them on.....just jump on the bashing bandwagon.........why respond to a post asking for information and then not give any???
Propane fumigation, with a system that can control the amount of propane being delivered, is a very safe and effective way to increase mpg and horsepower. When the amount of propane can be varied, not just on or off and can be controlled with a constant monitoring source, then mpg gains can be realized. The idea behind proper propane fumigation/injection for mileage was never intended to displace diesel with propane, it is to use a "small" amount of propane at a given boost pressure to assist in the complete combustion of the diesel fuel. The propane is NOT making the power, it is it's effect on the diesel fuel, that the power and mpg increases come from and that is simply from a more complete burn. Even OTR trucks are getting "net" gains of 1-2 mpg and they use considerably more propane than our trucks do. It's all in how it is delivered.
Propane was also not intended to be used as Nitrous. A little is good, more does not mean better or more power. It is excess beyond what it takes to burn the diesel and just as too much #2, from large injectors, or nitrous, or methanol will cause problems so can too much propane .
Keep the timing out of the programming (which increases heat) , with or without propane, especially if you have PMR"s.
