Only thing I dislike about the Crane XRi unit is that little potentiometer to set the RPM limit. With my eyes 6,000, 6,200, and 6,400 all look about the same when eyeballing it. Other than that, it has been a reliable unit with no problems in the 10,000+ or so miles it has been on the 2+2.
The chart looks like the results of a smaller cam. Torque peak at 3,200 RPM doesn't sound right, and I would vote that the cam is really advanced.
