FI seems to fall into the law of diminishing returns. Is MPFI the best / ultimate way to go? Probably. Do you pay for it? Absolutely.

Will TBI get you most of the benefits for less money? Probably. Seems like a good example of the Pareto principle - 80% of the benefit for 20% of the cost.

IMO Carburetor < TBI < MPFI (in benefits as well as $$). If cost is no object (when I win the lottery) I'm going MPFI. Until then TBI is on my radar screen.

Only you can decide what's good enough for you, and whether the extra $$ of MPFI is worth it over TBI.
