I would not do a dry shot. You would have to inject the Nitrous in front of the MAF sensor if you car has one and Im not sure if that would work for a TPI. The kit you have is probably a universal kit and not one for TPI. Every kit Ive seen and the NOS kit I have has a Nitrous/ fuel plate that mounts in between the throttle body and intake. I would return your kit or sell it and get the proper TPI Nitrous system like one from NOS Part #: 05151NOS.
