Acutally, i do care quite a bit, thanks orb for your insight. Now, what does that mean in layman's terms?

And is there a loss in low-end power from this mod AT ALL? There seems a lack of "sure" knowledge on this point. i took it off and then re-attached it after 2 weeks or so. What's your take on this modification?
