O2 Sensors and 330 OHM Resistors

There is a lot of talk about this issue, but my question is does it really make a difference for the weekend rider to do this mod? When I bought my VFR it had this mod done and I removed it, changing it back to factory spec. I do notice the flat spot or change in the engine when riding at freeway speeds but it does not bother me much. In fact I have read that its the ECM trying to save fuel, which to me is a good thing on a longer ride. So why would I want to remove it?
