Disconnect the cables from the exhaust flap, and try Dynamic mode.
After that, just ride it - throttle by wire will always feel slightly different to a cable throttle, if only because the weight is different because there's no cable to pull. If you still don't like it after you've given it a fair chance, then you have your answer! Both have their advantages, I have owned both and personally prefer the Euro5 (feels similar to how my Euro3 did with a quick throttle cam IMO).
