No expert here, but I am a regular watcher of the show Engine Masters. A topic that has been discussed there several times is the difference in air/fuel ratio from cylinder to cylinder. They point out that a MPFI is the way to go to solve that problem IF you have an O2 sensor on every exhaust pipe. Otherwise, the computer cannot take full advantage of the multiple injectors. The alternatives (i.e., carburetor or TBI) need to be tuned to protect the leanest cylinders for prolonged wide open throttle use, resulting in something less that the maximum possible peak power. ... So IMHO, if you plan on prolonged wide open throttle AND eight O2 sensors, then MPFI is the best choice. Otherwise, why bother.
