I am an INFJ with high Te. So much so that there are some people here who believe me to be an INTJ in disguise. I am an INFJ though, and this has to do with the fact that my motivations are infact based on Fe's principals, and back up of Ti. Fe is about creating harmony, uniformity, groups, etc. I very much do this all the time. However I often do it in the absence of emotion. This is very often why I seem Te like, and score with high Te. To me my emotions will get in the way of clear thinking and clear judgement calls. To me it would be unfair to inject my illogical emotional opinions into situations. I go to great lengths to put them aside. That need to be "fair" though, comes from Fe, it is a very strong Fe motivation because I must be fair to everyone else around me, for their sake. Te doesn't think like that.
I still go through the loops and internal processes of Fe, not Te. Te is based on complete objective principals, plans, and systems. I don't run through them like that. Te is very fast and very efficent. Fe isn't. This is because Te doesn't need to go through every minutia logistical logical detail in order to set everything spinning and into motion. Fe doesn't really either, but it often has to in order to plan. It sends it through Ti to extract those details in order to function. Te will send everything through Fi to extract emotional importance and worth. I simply do not need to do that, and if anything I do that first with Fe and either chuck it, or involve it with everything.
In reality you can't really be an INFJ with Te or an INTJ with Fe. It just appears like it depending on how much junk each throws through Ti or Fi. As I want my Fe to be as efficent, clear, nonjudgemental and efficent as possible, it gets filtered through Ti quite a bit. However it doesn't end at Ti for me which is often why it doesn't appear like Ti. This further backs up my persona that I am pretty much a bureaucrat's dream. I don't go linearly from Ni to Fe to Ti to Se, I go all over the map with a redicuolus amount of checks and balances to insure that it is completed right, and done efficently. MBTI doesn't judge on motivation very much, other personality indicators do that. I am very much a 1w2 which is why I am so heavily based on efficency and rightness, hence the bureaucratic loops. Not all INFJ's are 1w2's and I know very few on here who are, so this is why my methods of using my function is out of the ordinary.
