F22C 88k miles - stock motor. Surprisingly, no leaks anywhere.

Between cylinder 2 and 4, there is a 9.62% variance.

Are the compression numbers a bit too ambitious?

This test was performed after driving a few miles.

 

Never seen numbers that high. Maybe the gauge calibration?

Anyway, what is important is the variance, and there isn't any worrying levels of imbalance here...
