With the 210 tune, there is practically no re-learn process to speak of. It is pretty tame. The 275v4 needs it regardless whether or not you have the new TCM. It is a different animal. The 275v3 that I got months ago is also a lot more tame than the new 275v4.
I didn't bother getting a 310 tune to use without a TCM, because my truck is a very early 2008, and the 310 doesn't like them apparently. I have a TCM and the 310 tune. It's so powerful, it's kind of ridiculous. The shifts are sooo firm that you feel like you are going to chip a tooth. You kind of feel like you need a bite guard to drive it.
I feel like my truck might explode while running it. I actually put the stock TCM back in, and retuned it to the 210.
