FX DRS Tactical Tuning Issue

Evidently this gun really likes this tune. I shoot 1” paper dots stuck to gongs at 55, 60 and 75ds; today I was hitting the dots at 75yds, then I was able to hit the left over pieces that were 1/4”-1/2” size. With a fill of 225bar, it is at 150bar after 30 shots. First shot after sitting or filling is always low power but spot on if I dry fire the first shot.
 
I have made a thread here on how to solve that first slow shot. It involves some work that I wont recommend for people that arent working on their airrifles.
