Zip tied both ends and no issues since.

This would be my suggestion as well. When we first installed BPB on our shop car, we ran into this issue. If you have a leak there, you will have stalling issues. Definitely worth checking out. It's unlikely to be a tune issue since the BPB maps are 99% the same as the standard OTS maps. Only difference is some minor tweaks to fuel/timing/vvt at high RPM. Definitely wouldn't introduce any idle issues.
