I think every car might be differnt but i hit 8.5psi and its in the low 40s and no fuel cut i think its the backpressure in my exhuast that saves me i could see if you have larger exhaust system less back pressure that your going to spike your maf and hit fuel cut. Does that make sense?
You shouldn't hit fuel cut if you have ssafc. It's also a fcd. I run 12-14 all winter no problems in Chicago.
I often wounder if its dependant on what tune or flash your on from the dealer that decides where boost/fuel cut is at.
