When using a small rear housing the wastegate has do do more work. The reason being it takes less exhaust gas to spin the turbine up to the desired rpm(boost level).Therefore the wastegate needs to bypass a lot of exhaust gas.
Bigger is always better when it comes to wastegates,38mm is a decent size gate but personally id be going for something a little bigger, or using a larger turbo/exhaust housing to begin with
