Ok i got one for ya guys i herd that when my truck is idleing that the vp shuts off and only uses what fuel the lp pushes. Ok if thats true my truck now idles right inbetween maybe a tad less than 900 and a grand if i was to turn down my raptor 150 would that idle settle down to 900 or a little less

I wouldn't think that the lp has enough pressure to fire the injector or know which injector to fire.

no i dont think that the lp would have enough pres to fire the inj 15psi is def not enough to do so.

your injectors take alot more pressure to fire than the air dog will ever make so Id say no way

It should take 4500psi for the injectors to pop. Im pretty sure that isnt going to happen from a lift pump.

no i dont think so either

ok thats what i thought but i was reading on another thread in this section some one was asking how much fuel does the trucks use sitting at idle and some one said what i described above but any ways is there a way to make it idle a little less or whats the normal range for rpms

if thats what yer after just tool on down to the delership and get the 3cylender ideal turned on that might save you some

na i was just curiouse i just wanted to make sure that was normal bec. it used to idle at 800 befor the VP raptor 150 and quad addr
So whats that 3 cylender idle thing all about never herd it befor

how do they turn it on.. does it cost money?? does it take longer to reach operating temps???

It will cost u some to have the dealer to program it in and the temp will warm up faster because the engine is working harder because only half of the cyls are firing. plus you get the high idle for warm up. around 1200 then when it reaches operating temp it returns to normal. Not sure how much it would cost from the dealer to program it in prob i would say about an hours time so dep on the dealer i would say $75-100 IDK just a guess on that tho.

i dont know if i would do that.

just find a buddy with a smarty, have him flash a tune on it and take it back to stock, that will give you the updated programming with the high idle at anything under 30 degrees and 3 cylinder idle under 0 degrees.

Oh yea i forgot about the smartys bein able to do that as well.
