Ok sorry it took so long but my unit has been activated and i havent had a lot of time to get to a computer, heres the deal the kit is a nx kit, universal ford efi, adjustable from 35hp thru to 150hp, comes shipped with empty bottle so you will have to find your local distributor in order to have the bottle filled, comes with a liquid filled bottle guage and all installation hardware for $550.00 plus you pay for shipping and handling. you should be able to fill the bottle at a dragstrip near you. any more questions hopefully i can get the answers to you faster. we have to have an order of at least $2500.00 to get this price, otherwise the kits are $775.00 a piece through nitrous express with out the guage. we've installed several of these kits on mustangs and had excellent experience with them, well laid out instructions and all hardware needed in kits
