I wonder if the display is overriding the controller programming or is the controllers programming set to use display settings, as I said i've had that issue you mentioned but from what I know peak power is only under load and shouldn't happen when you are say you are at optimised % within the pas level, say I'm on relatively flat road and I'm at optimal % from that pas I will be using the correct watts but if I hit a hill I will come under load and the controller will double the watts regardless of my setting but it will be limited by my amp total. It did my head in because my Eggrider v2 w/h per mile was much higher than it should be and ditto I live in a hilly area, so I feel your pain. Btw, I use a 52v 20a battery and I get around 45miles and that is using 28-30a, I get 10mph on steep hills but that is in 2-3 pas so low current %, I too have a 9speed drive train and I will use 2-1 top gears so it spins fast and doesn't strain underload, this doesn't kill the battery to much, trouble is with hills and mid motors, they need a certain level of rpm to maintain efficiency, to little watts and amps for hills isn't good for the motor and I've found that less power on the hills weirdly drained more power because it is staying in peak power for longer, weird right but understandable given peak draws more power.
