your P1 will go to 18-20#'s but will only be affective to bout 16#'s.
i suggest buy a 255 inline fuel pump and that should carry you past the limits of the P1 and a 100 shot.
as for the N2O, a wet kit spays N2O and fuel at the same time and will pull fuel from the fuel rail at the schrader valve, as to where a dry kit will only spray N20, and makes the computer compensate for more fuel through the injectors.
usually a 35 shot will get you about 50-75hp and 75-100tq.
plus it will lower the intake temps to allow for more timing.
you will be more than happy with the power you are making now plus a 50 or 75 shot. BTW a 255 inline FP will cost you bout $120-150
