Okay, so it turns out a lot of people run propane injection pre-turbo, and if you get intake backfire, well, it usually blows off some pipes and that's that, so no biggie there (assuming things are working properly and this isn't happening all the time).
I'm still curious as to why you are saying I would need the boost reference for the mixer - it wouldn't be operating under boost, so it would be mixing just like a naturally aspirated engine.

You can ignore this question...I found out the answer. For some reason I thought they were much more simplified devices that didn't have all the circuits gasoline carbs do. I think I got that idea from looking at some simple propane assist systems for trucks. But they are actually fully functioning carburators, just designed for propane.
