Retrovolt Jasion Pro Need Advice

Hi all, my fiance got me a Retrovolt Pro made by Jasion for christmas, and I couldn't be happier. However it seems to only top out at 25mph, and it says it's got a 52v battery with a 2000w motor. I went into the "p" settings, where you hold plus and minus, but p08 (the one that online says to change to edit your speed cap) is disabled. Any step by step instructions on how to get to p08? I've been googling and looking at youtube videos and none of them seem to have the same firmware as me. The screen style is SW900 / UKC-style “big digits + PAS in the middle” display family firmware, and it says it might be hidden and I have to enter some menu to edit it. I just want to do 30-35mph. Thank you.
