dry shot/bottle pressure/tune question ok, down in florida the temps can get real hot real quick. with that being said i know the ideal pressure is around 1050 for spraying, but lets set up this situation:
if i have my car tuned at the ideal pressure at 1050, and have the appropriate timing and fuel changes made, but when i go to spray the pressure is above or below will it effect how my car runs negatively? knowing the higher the pressure the more it flows and the inverse, since the nitrous is passing through the maf, will the injectors input the right amount of fuel even if its not on the same pressure it was tuned at?

One of the many benifits of a dry hit, a/f will stay relative with low or high bottle pressure, given that your base tune is set-up correctly for desired a/f. You can run your bottle all the way to 0 pressure and no worry, you'll just get less and less additional power (try that with a wet hit). Same for adding pressure, but only to a point, as to high and you'll start to loose power from nitrous turning to vaporous mix. So a better way would be to jet your hit to the rwhp desired @ 900/950psi, then you can control additional heat (if wired this way, mine is) which equals higher b/p and thus a larger hp hit without changing jets. Keep from going over about 1050 and you'll be fine. 
Oh one other benifit of starting with a lower b/p is the fact that you'll drop less pressure per run.
