the wastegate is a mechanism that takes signal pressure air from the turbo, and at a set point, releases the pressure via a spring through the turbo down pipe, and out the exhaust, preventing the turbo from spooling itself too high and causing damage to itself or your engine. "shimming" the wastegate usually strengthens the notoriously weak spring inside the 951 wastegate, so that it doesnt open with too little pressure, causing turbo lag. if you're running the stock gate, you're probably losing pressure the faster you go. hope i could help.
