Many complaints with modern enthusiast cars come down to modern tuning like rev hang, throttle response, shift logic. Most of these are easily remedied by aftermarket tunes. However the one thing that there appears to be no solutions for is EPS tuning. Steering adjustments via software are clearly possible within the car as manufacturers adjust the weighting when switching drive modes. And even the same racks will have better/worse tuning in different cars. I believe some Porsche’s have an EPS tuning swap that is done in the aftermarket. So why isn’t it more ubiquitous? Every deficiency in a car seems to have an aftermarket solution. But with steering you pretty much can do alignment and tires then you’re SOL.
