Safety first..., What boost to set it at? Options

[DSM5]

MY car is stock when it comes to fuel mods. So what would be a safe setting for my new MBC? I was thinking around 14psi.

I'm spiking at 15, then it comes back down to 12-13, thanks turboXS(but hey it was free).  I'm not going any higher for awhile, but when I looked at my log, my O2 trim said i was running rich.

your boost controller isn't the reason you are creeping. where it is located might be a part of it, but a turboback exhaust and proper port work would decrease creep and hold the peak alot better,

and what is rich to you? encountering any fuel cut at 15psi? any knock? My DSM was running 16psi with a few mods and was hitting fuel cut hard in the cold weather.

Sounds like he is complaining about booost spike rather than boost creep. Two different things. Boost spike can be caused by the mbc. But if its only spiking to 15 psi, I don't think you have anything to worry about. I've always had good even boost control running my mbc between the compressor outlet nipple and the wastegate actuator.
