Default wastegates and emap
this is probably a stupid question, but i have been reading up on emap (pre-turbo exhaust pressure) lately and got to thinking.. on an internal wg setup, what stops this from opening your wastegate before target boost is reached? i figured this is not a problem on external wg, because usually they open against the flow of exhaust, and/or they have dual ports so boost pressure works to keep the valve closed before target boost is reached

im running a 60-1/p-trim S5 hybrid with the stock 6psi wg actuator. but im running 15 psi, so the emap at that level has to be like 15psi minimum, right? why doesnt it push open the 6 psi wg door and let all the exhaust out?
