I was skeptical of your typing at first but the more I read of your posts, the more possible it seems. So yes, maybe, probably.
Why do you think you have "ridiculous" Fi?
I've just been under the impression that my Fi shouldn't surpass Si in use, but I guess it makes sense. I was probably sticking too close to the Ti-Ne-Si-Fe ordering, in thought. I think the Fi is probably mostly a result of Ti/Ne coming up with a set of ideals, and since I was raised in a Fi/Ne - heavy family. I'm fairly certain now that INTP is correct, though. And I guess it's also natural that I completely hate Fe, and would always prefer Fi over it.
I could have sworn that you weren't always listed as ENTJ?
Ti = Ne > Ni > Si > Te = Fi > Se > Fe
