you shift like 100 less because your rpms would rise faster. Shifting way earlier really doesn't help. Yes you pick up more at 4000 rpm than 6000 because the air is more dense, I believe.

Good topic. I just ordered an NX kit myself 
and will be taking notes since I'm a nitrous newb. Silver, I have a 98 M6 Z28 so we have similar set ups.
What are you track times/dyno numbers? With 4.10s I see, which can be wicked, no traction issues?
I'm heads/cammed too and put 413 to the rear. That will change soon

Actually you need to shift right before the cam makes it's peak power, so it depends on your cam. You need to dyno the car, no dyno tricks, see where you are making peak power and shift a couple of hundred RPM before that so that you don't lose to much shift extension.

Now I shift at 6600 and my traps are 118-high 119's. My ET also got better.
on my stock cam I have the window to go off at 5800, and then shifting on the stocker around 6200 rpm(cam), but on my tr225, I will most lilkely be in the 6400 range off and then shifting in like the 6700's. hope this is some help
