I own a '91 MX6 Turbo GT that is completely stock. Recently the car has been over boosting in 4th and 5th gear when the turbo builds pressure slowly, resulting in engine cutout with accompanied over boost alarm. It seems as if the waste gate is inoperative. Has anyone seen this problem before with suggestions as to what to check or do. Engine comes up clean on codes when running diagnostics. Please help..........

Check the pressure hoses going to and from the boost control soloniod. When they get old they sometimes develop cracks which basically act like a bleeder valve.
