Need to know.
Let's say that you're working with a turbo which has the internal wastegate set at 8psi but you don't want to run that much of boost in your turbo setup, instead you want to run maybe 6-7 psi of boost.
How can you lower the boost ?

You need to lengthen the actuator arm to lower the boost. Some people re-thread the arms and use nuts and bolts to get it where they want it, others use washers to bring the actuator closer to the wastegate. Just remember, when you do this you are increasing spool time by a large amount. You are creating a leak in the exhaust so you won't have as much exhaust gases to spool the turbo.

Well, the leak in the exhaust is created by moving the wastegate actuator. When you do that, you open the wastegate which re-routes exhaust gas to go around the turbine, which also lowers your boost. It just sucks because you create an ass load of lag that way. Your best bet would be to buy the right sized actuator. :?
