ISFP and ESFP have Fi and Te, but you'd circle the earth to find one that I had higher Te than Fi. It might be more likely than you're INTJ, who has higher Fi than some. Would Te being your strongest function?
Oh, and this would explain the stubbornness with that Harry Potter thread jk (not really)
Te could be my strongest function, but I think Ne is stronger; though Ne, Fi and Te are all pretty well-balanced. In any case I couldn't possibly be an INTJ or an ENTJ, because my Ni sucks.
