Since this is the FAQ, and free mods comes up a lot, I figured we should post them, and how you did them.
I'll start first.

1) Resonator box removal.  Gives the car a unique growl and possibly some power.  But faster revving is pretty much agreed on.  
   How To: Open air filter box.  Remove air filter.  Unbolt the 3 or 4 bolts on the bottom and remove the air filter box.  Then there is another black box under / beside the filter box.  That unbolts too.  Remove that, and throw it away.  Bolt the filter box back on and re-install filter.  Most people also remove the black hood scoop thing to.
   What Rampid360 and I did:  Removed the resonator box.  Remove the hood scoop and feed it through the hole in the engine bay under the resonator box.  Hook it up to the filter box.  Then draw a cutting line, with the "mouth" opening towards the bumper.  Remove the scoop, and cut it.  Re-install the scoop, and now you have a home made CAI for free.

2) Automatic transmissions ONLY:  On both s13 and s14 auto trannys, there is a circuit, that when broke, removes some fluid weight from the tranny and shifts faster and harder.  GTech meter shaved .2 seconds off.... but then again, GTech sucks.  This has been said by Nismo to not cause any harm, and said by people that anything harder is going to lead to broken stuff.
     How To: On the right side of the engine bay, near the strut tower, really close to the fender, there is a grey connector.  Unclip that.  There is only one, and yes, it is a pain to unclip.  Turn on your car, and drive away.  
Please note: This will cause an s14 check engine light to come on.  Read the FAQ about ecu resetting to clear the code.

Ok.  I will try a few other things soon, and edit this post and add as I need to.  If other people would add what they did, that would be appreciated!  And I know someone has done the hyper-blinker here... so tell how you did it.  I KNOW that you don't need a kit, and its free.
-Jeff
