I have my nitrous set up after the maf meter so that it leans out (it's the easiest on the fuel system on my style car). If you use a dry shot after the maf meter than you will definately lean it out, just make sure you back off timing. I have tested 50-200 shot, and I can TELL you that for every 50 shot the a/f leans out by 1/2 a point (so on a 200 shot I run 9.0a/f off spray, when the spray hits it goes to 11.0, when I had a 100 shot I ran the a/f at 10.1 and it leaned out to 11.1:1). This is with 1000-1150psi in the bottle.
Just make sure you have injectors and a pump that are up to the task! (don't know how much power you are making or your fuel mods).
HOWEVER, as previously stated, a tune would probably be your best idea.
