Long story why, but I am going from a neuspeed power module to a jb4. Do I need to remove the neuspeed and let the car adapt to stock before installing the jb4? Or will the car adapt if I go straight to the jb4?

I think the ECU will adapt no matter what you do. I'd imagine youd be fine with a straight sway and then the ECU will later adapt to the JB4 after x miles

I don't think it's an issue. The only thing I know of that the car's ECU stores are long-term fuel trims. They'll adapt to the JP4 after driving for a while. If you're REALLY concerned just set the JB4 to stock and drive around for a day to reset them to stock. That's what I would do anyway, just to make sure all of the connections are tight before increasing the boost.

I would just disconnect the battery while installing the jb4 (you'll be fishing through the firewall already) which should reset stored values.

TLDR; you should be fine to just install it without doing anything fancy
