Well, like I said it's all in how much you want to spend.
You could plunk down almost 2k on an AEM EMS; but you'll likely be getting support only from AEM. Or you can usea an adjustable FPR with an SFMU and some kind of controller to tune it (SAFC has been used for this, but it isn't a very good way to do it). Or, you can drop around $350-400 on MegaSquirt (You'll need the 1:1 FPR here too)and have full control over fuel and spark; but, you'll have to know what you are doing. (or know someone that does )

Edited - Because I cannot spell before 0900.
