I have lost a couple of races that I should have won. Some members suggestged that I check my actuator. Thanks to the nice photos on the site, I did this. When I hit the rpm threshold, the actuator does engage (had my brother watch as I rev'd in neutral). One of the posts said that the actuator should make a thud sound when manually engaged, as the secondary intake opens. I manually turned the actuator, but no sound. Is it dead or am I just a shitty driver?
