hey guys i got a 1999 cummins and i found a bully dog diesel propane injection kit for around 400 bucks. whats is the pros and cons about it and do i need head studs and o ring head for this like for NOS?
 
makes mileage go up, my buddy has got it on his 06 dodge one of them bully dogs kits. his is stock had it for about 2 years, no problems. but i dont know what'll happen if you get crazy with it or anything.
 
For $400, you can buy an Edge Comp or Quadzilla Adrenaline. Either of those boxes will make more power than propane.
 
i already have the adrenaline. and im going to do a he351 retro fit and 100 hp injectors.

It will make your diesel MPG go up, but your combined MPG factoring in the propane will go down. If the propane is going for a good price you might save some pennies here and there but to put it on in hopes of saving fuel costs you may never even save enough to pay for the propane kit.
