Also,
Are you pressing very slowly the accel pedal for 3 or 4 times with the ignition on and engine off before cranking the engine after reflash or DTC clearing?
It helps a lot


About learning, csg Mike Is right, Ltft learning plays a big role in engine smoothness and pedal response
In my tune i keep ltft disabled all the time and basically in less than 5 minutes of driving my pedal goes ok
So after the clearings I never did that process. Just drove normally until car went back to normal. While having these issues and symptoms for the last 7 months, whenever I disconnected the battery and then drove the car for a few days, the car would actually feel a little better and smoother for those few days. The MPG would actually hovering around the mid 21's for those few days. After a few days when the car went back to its usual state after the re learn process, the car felt horrible once again and even the MPG dropped significantly. I'm currently down to 18.2 and slowly going down. I was also clearly running out of fuel much much quicker then before.
