DB Killer = Remove it, and hammer the tube inside of DB killer so that “hole is smaller”   (about dimensions of 10 Pence UK coin)
This means less gas leave bike
Better lower end torque (very tiny boost) but DYNO will notice.

Also Jets  90 and 92.5 are most optimal .    95 and 97.5 is a lot!

Then try DYNO again 🙂
