New affordable Fuel Injection

I spent $800 on a complete 99 Durango 5.9 46RE. Kept the leather interior and sold/scrapped the rest out for $500. I sell Tanks Inc so its a bit cheaper than for you guys but not much. So say I have $500 in tank, pump, sender and fuel lines plus the $300 for the rest. I am currently looking at $800 for multi port injection, which happened to come with a 5.9 and OD trans. I can get parts,including PCM, at any parts store for dirt cheap. I think thats cheaper than a carb any day of the week!
Goldduster, assuming you are running magnum stuff, what pcm are you using?
