Some of that depends on who you ask. CFI isn't much different from the TBI found in our trucks, once you understand it. If you adapt it to run a 7747 ECM, it performs similarly to TBI. The main difference is that it has 2 throttle bodies with a single blade and injector each, where TBI has a single throttle body with 2 blades and 2 injectors. The reason they are so maligned is that the ECM was pretty primitive. When it works, it works pretty well.

Doing a TPI swap and an LS swap are really apples and oranges. Most of your accessories, mounts, and trans will work if you are doing the TPI swap. Not so much with the LS swap. While the LS swap will probably net you more power, one would have to look at their mechanical abilities and see if it is for them. I like the look of the TPI swap, but that is just me.
