Well, I'm not really interested in reinventing the wheel. Reading through the FM instructions, it doesn't seem like there's a whole lot of room for less boost if there's too much. The wastegate actuator can be shimmed a little bit. I can certainly reduce the timing. Otherwise, there's just not much in the way of tuning options if it doesn't work out. Not sure if the 10.5:1 pistons are a terrible idea or not?

You can swap the wastegate actuator for one with a lighter-weight spring in it that holds less boost, but I don't know if anyone makes one less than the 8-ish that the standard actuators normally run.
If you are concerned about the combustion chamber volume after machining and the effect of that on the compression ratio, you could measure the chambers and calculate the actual CR with the various offerings on the market.
Standalone isnt *that* hard if you end up with no other good options.
