Your results seem pretty typical actually. When Karl Jung came up with personality archetypes, he only included the dominant and secondary functions because he knew that everyone had all 8 of the functions at various levels. When the Myers Briggs test was made, it was designed with this in mind - attempting to define the dominant Judging and Perceiving functions, not the remaining functions. It wasn't until later that the function orders were added to types by other psychologists, and to be honest, they're rather assumptive.
The fact that your top two functions are Ne and Fi are indicative of being an ENFP. A lot of people have results that are atypical of the standard model on that test. My functions usually test as Ni>Fe>Fi>Ti>Ne>Se>Te>Si, which is only INFJ by the first two functions. The reason for this is simple. A person's top J and top P functions will always slant the rest of the functions because you start your reasoning processes with them. The other function results are just approximations at best because they're so strongly influenced by the functions ahead of them.
Heh, and I'm realizing I'm probably an INFJ after all. My top two functions are Ni and Fe. They just have a capacity to take turns driving, which caused me a little confusion.
