I agree brother, not like you can easily (mechanically) go back to TBI anyways, I don't see why anyone would want to play "just the tip" with this particular conversion. I was going to get a second computer and memcal to do this myself, but then after a few minutes of thinking about it, it hit me... WHY? If I have the kinda time it takes to go back to the TBI intake, then I'll have the truck parked and enough time to convert the ECM back also. Hell the ECM changes are the fastest out of the whole ordeal.

Watching this thread myself, I have about 90% of what it takes to do the conversion on my Suburban. Just need to find the proper RP/Mercruiser injectors and a few other chicken shit items so I can get this thing back together in a timely manner. I hate letting a vehicle sit an extended period of time.
