Shows how to build a propane injection kit to use on a diesel for less than 150 bucks! I used parts from ebay, a local rv store and Ace Hardware.
The system has been set up for a power increase, so when you hit the switch, it really sets you back. Some friends of mine have the factory built systems and have them set a little lower.
They claim the mileage increase is the best single thing they have done for their trucks and that it far outweighs the cost of the propane.
As I said before, this propane injection system is set up closer to the max you would want to add, and it increases the horsepower by probably about 100 I'm guessing.
The Superchips Max Microtuner that is installed in the truck is supposed to add about 50-70 horses depending on which setting you use. Flipping the propane switch adds a lot more than that by feel. I rarely ever use the thing, but almost every year, I go down to Bandimere Speedway for truck fest and have some fun.
The best times I've got with this old truck, fuel tank, tool box and all was in the high 15's. Not bad for an 8,000lbs beast with almost 200K!!
