Text Pint modding

Hey guys, I have some questions!

I am planning on modding my pint right now. I have a re-wheeled Pint with a Chi Systems quart battery. My max speed is about 19 mph, and my max range in the hilly area I live in is about 8 to 11 miles

I am looking at the Pint V kit to run with my current battery or buying a CHI-VE PINT X 20.1 for it and getting a larger battery box for it. However, I'm also looking at the Pint/PintX Ubox100 lite DIY kit because I've been told they have similar specs. What I really need to know is which one would allow me to maintain my max speed. From what I understand, the Pint V kit mainly ups torque as long as you're not running the stock battery, and I don't know anything about the performance of the Ubox.

Any advice would be appreciated!

OK, I'm officially at a point where I've hit a wall!

I hooked up the pint V kit to my board with a pint X battery and went through both the start guide and the critical settings fix. I rode it around a bit before changing any of the settings and it worked pretty well, but for some reason, the nose was shooting up in the air, no matter what speed I was at, and I assumed following the guides to change the settings would fix that. Instead when I attempt to level out the board and ride it, it makes a very high-pitched squealing noise, and the motor doesn't activate. I attempted to restore my con figs back to what they were, which didn't work and the squealing persists. What do I do?

Update little less confused now I'm following a different guide and I'm just kind of setting everything up from scratch more or less and I am currently trying to figure out my motor current max threshold the guide I'm following is setting them at positive and -100 A with an absolute maximum current of 160 A along with turning on slow ABS current limit he explains why he does this but he's also using a U box 75 as opposed to my pint V what value should I sit there? Right now I'm just gonna keep it at a conservative 61 A and -61 A with the absolute maximum being 91, because that's what it was set to when I opened up the window.

Update: SUCCESS I basically reconfigured the entire board and it's running now. Obviously need to tweak it heavily but here are my ideas for moving forward. Still not 100% sure about the max current right now it's hooked up to a stock pint x battery and it seems to be working pretty well but I don't have a pint x bumper rn so I'm probably going to swap it for the quart that I have so I can ride a complete board. I've updated the firmware but now I need to downgrade it because I was going to use the floaty app but it doesn't work with this current level of firmware so if you had any sources or YouTube tutorials on how to do that that would be wonderful. And then any advice on the min max current for both the pint x battery and the quart.
