Yes, and once you find it where it runs best, to make it perfect, order a new cam to match your findings. It will be even better.

You use the adjustable sprocket to test a camshaft that is not optimal. To find out what your engine needs.

For fine tuning (which won't result in huge power gains) you may need to "dial in" the cam. You can use offset keys to do this, because you'll never need to adjust it again once dialed-in.
