But am wondering does it give some MPG benefits misting 1-2psi of propane into the airbox?

Most importantly, is it safe? Is it safe compressing LPG through the turbo? What about the combustion chambers, can the head handle burning propane in small amounts with no extra wear?

I'm just looking for a simple diy kit to help with mileage. They say we might see $5/gal for regular gas this summer, diesel will be through the roof!

Also, it seems like a boost pressure switch of some kind would be the best way to turn on the propane. Something that activates the propane when there's 5psi of boost pressure. But it would be easier to put in an oil pressure switch that turned it on when the engine started. Would it be bad to idle the truck with propane? What about shutting it off with the propane going?

Any info would be appreciated.
