There is too much slack/slop on the fly by wire throttles which is removed when fitting these kits. In the olden days you'd take it out by adjusting the cable...FBW has no cable. I personally found it made big difference when reintroducing the throttle mid-corner.
As it happens I am suffering the Kawasaki slack problem at the moment and my cables are tight. I’ve mostly solved it by reverting to the OEM throttle tube and housing because a ‘quick action throttle’ is just useless in racing I now realise. I’ve also altered the fuel map at mid revs and part throttle so that it’s not such a kick in the pants experience opening the throttle out of a corner. Still not completely solved by much better.
