ah, this is not a bleeder type !to my knowledge! it is a one in and one out. However it does have a third nipple with a foam filter i forsee that this is a simple solenoid used for several possible functions......GM likes to do that.

I have some at home i can take a pic of. i'm stupified by the "bleeder type" you mention

on my drag car i use the old school blitz unit, would you classify that as a bleeder type(i guess i would since it lies to the vacuum assisted spring to adjust boost) with this in mind i dont know what kind of solenoid you will find that is not a bleed type , thats what controls boost pressure from a wastegate is pressure/vacuum on the actuator. unless its a variable vane controller or some shoot
