Default Waste gate adjustment

Has anyone played with this mod?
Is it really worth it or does it screw up driveability and fuel mileage?

I've done it to my past two GTP'* and I'll probably do it to the Bonnie when I start modding it, I've never really noticed any drastic changes in power or gas mileage, but it can't hurt.

Yes there is an adjustment for the wide open position. It'* an allen screw. You don't want to touch that one.

I didn't notice any difference with the adjustment.
Maybe it only works when the actuator gets old and weak???

We did it to the SSEi, and to the GTP. It didn't make a noticable difference on either, but it couldn't have hurt anything. What it is really supposed to do is make it so it closes sooner so you get boost a millisecond or two earlier and it is supposed to open later so you have boost for a millisecond or two longer. It isn't really supposed to give you more boost as far as I know. It is kind of useless, but it takes like 2 minutes to do, so why not do it.
