TE input lag in LS mode; is this normal?

I just got my TE stick 2 days ago. It’s works perfectly except for one small issue that I just noticed. Whenever I put my toggle to left stick mode, I experience noticeable lag when my stick returns to neutral. That is, when my stick returns to neutral, the game takes half a second to realize that’s neutral and respond accordingly. This occurs when I make any quick stick movement. This happens on both the 360 and the PC, though it occurs less frequently on the PC. Does this happen with anyone else. Again, it’s only a minor problem since I can just put it in D-Pad mode, but it’s annoying nonetheless. Thanks in advance.
