some wastegates are adjustable, look at the above picture, you see the "screw".
you better take a manual boost controller, you will see the boost come up quicker (and sooner i thought).
i drove without wastegate (the wastegate was not connected but it was on), i controlled the boost with feul quantity, but i think my turbo was running the last miles also :wink: (with disconnected wastegaate you also will see less lag)
