Go with the Zex system for no other reason then they make a kit specifically for the mustang....it was so easy to put in it barely took me 4 hours. It is a wet system that uses 1 shark nozzle in the air intake tube. Adjustable from 75-175. When I got the car dynotuned, at 950 psi the kit delivered to the rear wheels 101 hp and 132 more ft-lbs of torque on the 100 hp setting. Now I run the 125hp setting with a SCT nitrous tune and Autolite HT0 plugs, which are 1 heat range colder. The kit also includes an adaptor to get fuel from off of the fuel rail. Also, the system has an arming switch, but also a wire that runs off of the TPS. Once armed, the system comes on automatically when you floor it. The system has worked flawlessly for me so far, with many passes at the track. You can see all of this in the picture attached....
