Max1775- You didn't say how big your propane tank is, nor how many miles you actually drove to empty it, but I'd venture a guess that you've got a lot of propane flowing. I have a tank that holds 8 gallons of liquid propane, and it typically lasts me 2000-2500 miles in everyday driving.

We're trying several different pressure settings on swithches. I like the nice constant power, instead of having it kick in like nitrous boost. I've tried 7 psi boost to start fueling and it feels like throwing the nitrous on a gas burner. Right now we're running without a pressure switch at all and it works great, but may be wasting some propane. Gonna have to check the exhaust and see, just haven't had a chance.
Variable feed, as the intake sucks more air, the valve releases more propane. Using a valve set at -1/2 inches water column. So the valve will not feed until intake goes below -1/2" w.c. Trying two regulators, one is vapor/ vapor and the other is liquid/vapor. I'm having better luck with the liquid converter supplying constant power, but still testing.
