What kind of boost controller is it (electronic or a simple adjustable pressure valve), and what pressure wastgate spring is being used?

You are going to have to put some of that "gearheadedness" into practice and troubleshoot your boost control circuit.

1) Check all hoses to and from the wastgate, controller, and where ever it picks up the boost signal (probably the intercooler) - check for loose hose clamps, hoses that are melted, torn, frayed, etc.

2) If nothing in the above checks is obvious, bypass the controller with a double sided hose barb, and then take the car for a drive and see if the problem is still there. If it isn't, then you know the controller is the problem and it either needs to be rebuilt or replaced.
