Is the stock ECU smart enough to recalibrate and optimize the car's performance when you have upgraded with certain mods....within reason of course?

I've read here some people have hit the "reset" button on the ECU by temporarily disconnecting the battery. Others have said the ECU will "learn" the new mods after a few hard pulls. Finally, others have went with an e-tune or dyno-tune.

I plan to put some drop-in K&N filters and just a new mid-pipe/muffler combo (with stock y-pipe). Will my ECU "learn" and optimize itself decently enough ???? I know tuning is better, but it is necessary?

Thanks,
