when using thepressure tool to see where crack pressure is..... is the waste gate supposed to hold pressure, ??? when im testing mine it cracks about 11-12 but will leak dowm .... its a new high end pressure gun and guage. i can pump it up and i stop when it moves arm slightly but then pressure slowly drops and gate closes.....

Are you using the turbosmart wastegate or factory? Assuming you’re using the turbo smart.

Got ya, yea the air from vacuum lines in the solinoid should actually force the wastegate shut untill the ecu says to open. Are you sure it’s not leaking out elsewhere since it bleeds down? Also without sled running it won’t make vacuum pressure to close the wastegate and hold it shut, I believe.turbo smart from TD with electronic controller
