It shouldn't be dying that easy. What kind of BOV do you have? Is it bypass or blow off?
I do stall a few times from shifting to neutral from speed, but I avoid that by staying in gear and slowing down that way. Typically I'll downshift a few times as well, and by the time I come to a stop and put it in neutral it's fine. It also helps fuel economy since the injectors cut off with the clutch in and the throttle closed, decelerating in gear.
Congrats on the install and how much boost you pushing and what do you have for fuel right now. I've run 5-6psi with no extra fuel for tens of thousands of miles, but don't rev much past 5000rpm till you get it properly rich.
