Deceleration below 3000 RPM 2022 Tracer 9 GT

[Artieb]

My 2022 Tracer runs perfectly and had first throttle tube recall and reflash for stalling issue done at dealer before delivery to me in 4/22 and has no issues in 16000 miles  other than weird drop in engine braking below 3000 rpm which I’ve learned to live with it but it’s not really correct 

now due to bring it in for O2 recall and would like to have this rpm issue addressed what should I ask for is there a reflash for this one and only issue afraid it may make it worse?
