Default Effect of loose wastegate actuator

... loose by like < 1mm.

From dyno data.



It reminds me of Hustler's log vs. Absurdflow manifold torque curves... maybe it didn't give the log a fair shake, it had a loose wastegate.

Are you talking about tolerances in the WG mechanism or user error? I'd refute your assertion regarding user-error and a loose wastegate, but when you consider my build thread I concede defeat. lol

So you are showing that a loose wastegate flapper will yield the same peak boost levels but just spool slower?
