will a car boost with stock map sensor in it?!
I am thinking it depends if you still have your MAF hooked up. Is this what you're asking? If you don't have your MAF hooked up, and you are just on your MAP sensor, it will not boost.
Someone correct me if I'm wrong. This is what my friends Procharged car did.

What my friends car did, was when he would get on it, it would go up in vacuum till it hit pretty much 0 psi, and then it would sound like a 2 step would, and not break 0 psi of boost, because he wasn't tuned for anything positive pressure.
So to answer your question, its not "Where does the boost magically go?" You MIGHT break 0 psi, but after that your engine will stall because you're not tuned to operate there, thus you will have no exhaust energy, thus stop spinning the turbo, thus no boost pressure.
Make sense?

I ran MAF with a stock MAP sensor at 10ish psi. The problem is that the computer can only read the MAF signal so far (maxing out the maf) Thats where you need to do one of 2 things. You can "over fuel" where the MAF runs out to avoid leaning out (MAF's/computer can only read so much CFM) or convert to a 2 or 3 bar SD tune. Your better off converting and going to SD from the start...I wish I did lol
