Perhaps the 2020 2 port models do gain something from JB4/JB+ on pump gas because they have lower compression and possibly different AFR targets as well.
The 6 port engines have higher compression and run at lambda, so any additional boost does not result in more power unless there is...
For spirited driving of any sorts, a stiffer sway bar at the front is counter productive.
I don't think much can be done for steering feel on an EPS. Perhaps tyres with stiffer side walls might do something.
