Soft rev limiter removal

Many engines have two limiters. A soft one that gently pulls fuel or timing as you
approach the limit, and a hard one that cuts abruptly at the mechanical ceiling.

The soft limiter makes the car pleasant to drive but blunts the last part of the rev
range, which matters if you are changing gear at the limiter on track. Removing it sharpens
that.

The hard limiter stays. It exists because valve springs, rods and bearings
have a limit, and going past it is expensive in a way that is not recoverable.
