You may not have realized the full benefit of C-11.The conventional wisdom among experienced C-11 users is that to be fast with it, you'll have to retard the ignition timing a couple of degrees and go up a couple of jet sizes. I don't know if a straight switch from Purple or Blue to C-11 (changing nothing else) would allow you to see all there might be to see.
