Hello, new Hisun Axis 500 owner here. I have a 2020 in the Mountains of North Carolina. It runs fine and I enjoy it but it seems to struggle on the hills. Granted I have one that is pretty steep but you could get out and walk faster than it goes up. I sometimes wonder that if I had anything in the bed it might not make it. So first question is, is this normal for these? Second question is, is there anything I can do about it? Maybe a power adder or chip tuning? Appreciate your thoughts
