Now we look at Lobe Separation Angle. This, combined with the duration, determines the valve overlap duration.

The x303 is ground with a 112 LSA, which is typical of most mild SBF cams. Here we narrow and widen it to 108 and 116, respectively.

Typically, narrowing the LSA increases power on the top end, while decreasing on the low. While this did occur here to some degree, the lines actually cross a couple of times. I think this indicates that we just about have this thing tweaked in.
