Usually the hardware (AFM and injectors) have capable of bigger flow rate, the load point will be lower / smaller.
The more flow capable compare to factory hardware, the more load point it will throw off.
if switching point is not tuned, the butterfly will delay in switching, the actual drive feeling is somewhat like a honda vtec kick in, the torque will suddenly increase , some torque lost before switching, feel flat but suddenly alive.
if switch point is tuned, the whole switch thing cannot be feel, the torque will smoothly increase without suddenly change, no flat spot, feels like more torque at 3,500 rpm to 4,500 rpm.
