A little more explanation please.
The wastegate actuator diaphram has one hose on its top side connected just after the throttle body and one hose on its bottom side connected to the boost control valve.
The boost control valve has another hose that is connected after the supercharger and a vent to atmosphere.
If you removed the hose from the bottom, where did you connect it to. And did you just leave the disconnected port on the wastegate actuator open?

Yes.....please clarify. I think we're on to something here. I'm also curious to see how my Jet Stage 2 deals with this. I'll start digging myself. I haven't changed my pulley yet, but the new intake is adding a bit more boost capability. There'* always a way to trick the PCM. Just have to find the best.

the hose on the bottom of the actuator is taken off`i looped it back to the vent on the wastegate actuator and leave the port on the bottom of the actuator open. what it does is a hose off of the vac tree on the front of the SC produces boost pressure and when the boost control sol. opens, it uses boost pressure to push the wastegate open. the top port on the actuator is before the sc and is just vac. when you open the throttle , you lose vac and the spring in the actuator closes the wastegate.i have yet to have a problem and my boost doesnt fall off anymore either . if anyone wants a pic , please send me an email and ill send you one of it

I want a pic of that......take the pic, and mark it up for the swap. I'm pretty sure I see what you did now, but I wanna be sure! You know my email already.

Hmmm.
The vent connection on the Boost solenoid is smaller than the actuator connection, so the hose is too loose.

Do you think it will work if I simply disconnect the hose from the lower actuator port and plug it as well as plug the solenoid vent ??
