Thus car would react the same when it comes to bucking with or without the pop-off as bleed is only active at WOT, no?

Goran, assuming this compressor configuration has air noise it's pressure output in this region is not steady. It's more like a sine wave. On test, a sensitive pressure readout will show this fluctuation. Aside from the fact this pulsing can cause all of the EFI problems you describe above, the phenomena is irregular, meaning todays ambient conditions are manageable but maybe not tomorrows. One day it's a steady sine wave the next a full surge or something in between.
