How much lower does the shift points need to be when using nitrous?

you mean timing? set rev limiter to 500rpms past peak HP.

If my shift points are set at 6400-6500 NA. Where to set on my nitrous tune?

I'm no expert, but I recall reading that peak power rpm shifts down around 500 rpm when on nitrous. No idea if size of shot changes that, or not. Do you have dyno sheets for NA and on the bottle? I'd try 6200 and adjust from there at the track.

It's going to depend on what the car likes. On motor I shift at 66 with my limiter set at 68. On the gas I shift at 63 so it doesn't get to close the window switch which is 36-66, by the time I see the shift light at 63 it's probably more like a 64 or 65 actual shift. I have a good friend that sprays a 160 shot and runs mid 9s, shifting his car at 73 and 63 nets the same mph and same et. I think it just takes some trial and error, obviously making sure the error is on the safe side with all safety features installed.

Part of it depends on the convertor too. Adding that kind of power can cause you to blow thru the convertor and the car will shift higher than the commanded shift points. But like others said, you need to see what your car likes.
