You pull timing and add fuel for nitrous, that is how you tune for it. An ideal nitrous tune is going to be richer (say 12.5 a/f instead of 13 to 1) and ya need to pull timing, 1 degree for every 25 hp from the n/a tune is a good general rule that's a safe starting point.

mine comes in at 3000 now. i am getting hp tuners on sunday and want to bump it up to 150 or 175. i have the hsw interface and nitrous controller but it only allows for 3 degrees to be pulled without adjsuting the iat if i am not mistaken. i wanted to know how high people are spinning the stock motor. i wouldnt want to burn nitrous if its not helping.

I have a stock 02 Z28 M6 with a dry kit on it spraying 100hp, I have a digital window switch and it comes on at 2600 and goes off at 6000 never been tuned, I have sprayed about 150lbs through it in the last year. I put it on the dyno last month to see what the shot was doing and it made 70 hp more to the wheels, on the graph there was a small spot at about 5000rpm were pcm put in a little knock retard but have never had a problem. It still has the factory lid and it's birth defects on it and the paper filter in it.
