Abnormal lag on 16g

[ishnish]

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

I like your theory. I have been trying to by heat blankets for all my hot parts. I have the stock heat shield for my turbine and o2 housing, and my downpipe before the flex section is wrapped with lava wrap. So far, still seeing creep. But gonna get blankets for the fp mani, turbine housing, and o2 housing. From there, we'll see what happens. Thank you
