I've done some basic bolt on upgrades with my 2016 challenger scatpack. Kooks longtubes with catless mids, 87mm TB, msd blaster coils, hellcat intake box, exhaust with a stage 1 tick performance built TR-6060. Ryan's canned tunes cleaned up throttle response, definitely high end torque and it seems just right in all the correct places. My car runs as it should. I love it and wouldn't change tuners ever. Next upgrades will be a good Tomahawk 2.0 cam kit, some head work and fuel management. Can't wait for that.
