Let us know how you get on with CJS, I genuinely think you can get 3-5 genuine wheel HP all through the mid range with a per cylinder detailed map. That will feel like I decent step. You won't get 10+ out of it unless there's something desperately wrong with the setup as standard. Good luck, PS I like a few others on here think mine is plenty quick enough on the road and don't struggle to keep with things, but I can appreciate that the bottom end fuelling is pretty rubbish and it still needs to be over 4.5k revs to get going.
I would have thought that if you are making progress you would never be below 4500rpm anyway???and generally Ducati mid range is stronger than IL4s
