Fuel Injection Specialties is in San Antone, their web site gives a good summary of Tuned Port Injection:

I would suggest that you find a source that sells you the entire unit including the controller. Then, you will avoid the finger pointing if something doesnt jive. Next, decide what your intent is going to be, looks, performance, economy, simplicity, whatever. Talk to a couple of vendors and dont buy until you talk to your chosen group.....most will say, "we'll fix you right up" but spend some time and learn the basics. Also, if you can find some local guys who have F.I., you can talk to them....especially about a vendor's tech help after the sale. Also, if you dont speak it yet, get up to speed on the lingo..... CPK, VSS, etc....just like computer nerds, the injection world has acronyms to make them feel special.

Next, when you have knowledge of the systems, assess your engine. Do you already have a crank sensor and a distributor that is setup for your chosen controller? Note that most higher-end controllers tie the ignition to the fuel.
For instance, AZ Speed and Marine builds a MSD air meter on a GMPP manifold with the injector bungs welded in. A MSD distributor is tied to the Mercury Marine controller. They sell the harness and everything. When done, it looks like a carbureted setup except for the fuel rails. We put one together, set the static timing, and it fired first lick. Most of the better sources sell very high quality harnesses with the good wire. Most of the injection systems use factory type sensors.

Once you have done one, you will enjoy the easy starting, smoother performance and other advantages of injection. Unless I was building a drag car, I would never go back to a carburetor.
