Yeah. My 14b and 16g both started at 7psi just hooked to the actuator with no boost controller.

I have varying theories about heat transfer, but basically with stock downpipe with all heat shielding intact you should not have boost creep. My prevailing thought is the piping should remain the same temperature or hotter than the gasses, so that the exhaust gasses do not try to rise back up into the turbine housing, and are expelled through the tail pipe
