I see in your sig you have a power commander. I would go with a wet system and keep it seperate from the EFI, very easy to do and makes good HP. I always ran the NOS Fogger and/or plate systems on my pro street/drag cars but I like the NX single cylinder system for the 700R, it has a nicer bottle mounting set up and better installation components IMHO.
If you go with a dry system you will need a controller to go with it like the boss noss system My self, I just am not that impressed with the dry systems or their components and I am not willing to give up my PCIII for anything.
Good luck with your choice.
