Yes, the exhaust manifold pressure can push past the wastegate, and it makes perfect sense that this problem is increased whenever you make your wastegate port larger (more surface area for the air to press against, yet the same actuator holding it back). A good EBC should be able to all but eliminate that problem since it will keep the pressure to the actuator low until it actually needs to start limiting boost.
