Tuner-gear-gear oil kit.

I am really considering this kit.. but I'm really wondering..


Do I need a tuner?


What exactly makes the tuner so worth that much money? Will I be able to use it effectivly and get any sort of gain out of my 5 speed with the mods in the sig? I will gradually mod and eventually get some sort of power adder.. but in the meantime.. I just don't know that the benefits are worth the cost at this point.

Maybe I'm just really wrong. I have NO clue about a tuner and how to work it, or what it does..


Educate me please!
