Agree with the guys above. Start with the basics
If you have ABS, you more than likely have a two stage booster. If you want to keep the power brakes, about the only thing you can do to improve “feel” is to swap to single stage booster. The single stage is commonly found in non-abs cars and does feel better. You’ll want to pull the hard lines as well and delete the ABS.
I did this on an older build and it definitely felt better.
My current build is going to go to manual brakes with the help of a “Chase Bays” brake booster delete
