Good work on the de-blinging! Looking 10 times better already.
With your question about the actuator, Im pretty sure there is nothing inside the actuator that can be twisted, even so there should be a nut below the end part of the actuator which is to tighten the end part once its at the right length. However, I wouldn't recommend adjusting it yourself as there is alot more to getting mfi (the pain in the arse that it is) to run sweet than the amount of boost its holding.
