so does anyone know of or use any performance chips in their tacos? this might sound a little newb but i am asking for my brother and i have heard to be careful about spending money on a one that doesn't improve anything. thanks for any input and again sorry if this is a newbie question.

Yes the newb question of all newb questions.

But no the none of the chips work on the taco. There is not alot of performance stuff that helps the taco short of getting a supercharger and a bunch of fuel mods to fool the computer.
