Yes I agree perhaps taking to an expert tuner is the correct answer, but no one has actually answered the original question for us have a go tinkerers (come on if we didn't tinker and blow them up the tuners have less cars to rebuild! lol)

I always get this mixed up, I assumed the more wound in the actuator is (making it shorter and harder to get back on) the more it would run more boost (only ever done half a turn at a time)
