Have you done a boost leak check?

boost leak checked and done.... i mean half throttle i'm able to reach almost full boost in higher gears...but once WOT comes along....the car would rush up in speed til about 4-5k RPM and then just fall on it's face...it feels like the motor just turned completely off, RPM drop and high hessitation and it gets really rough in the higher RPM's...

most likely its a before-turbo exhaust leak.

You haven't UP'd the boost have you?
