I'm impressed with the throttle response and linear power delivery as it is! You are saying the difference is extremely noticeable? Hmm I wasn't going to get one but now I'm intrigued...
It's virtually axiomatic that changing the intake flow and removing a significant amount of backpressure on the exhaust side will require re-mapping. We used to do it by changing the jet size on the carb(s); now with FI it's a re-map. However, I was quite surprised to find the CB ran without the lurching, popping, and other super-lean mixture faults when I put the 2Bros exhaust and K/N filter on with no FI mods. It wasn't perfect, but compared to other bikes I've made similar mods to, it ran quite well.
Having said all that, I returned it all to stock and I'm going to keep it that way. For me, the factory setup works. It's the smoothest power, lowest vibe, comfortable hour after hour bike I've owned with the possible exception of the VFR-800. Even that bike's V-4 would be no better than a tie for smooth power delivery.

So you've been to the Dark Side and returned, and are still happier with the stock settings?
You may be the best friend my mortgage overpayments ever had Spaceman!
