Dead pedal/sluggish feeling is reported as normal within a hundred or so miles of the reflash until the ECU relearns throttle/pedal positioning. It's probably that.
FWIW the 2017+ MT cars use a different exhaust and intake and I'm not sure if the stg 1 that comes bundled with the tablet is meant for it. Check open flash's website and see if you can't find one of their tunes for an MT2018 car, I'm pretty sure they have it, it should run better.
