No but if a piece of plastic is a piece of plastic, why not save the $25?

I dont know of any differences between Hondata or the other multitude of copies...anyone else have any information?

As for picking up power, not really...its moreso designed to prevent manifold heat soak, therefore decreasing IATs slightly in a situation where heatsoak would occur.

That, combined with a few other simple mods may allow a tuner to be a bit more aggressive...but other than that I wouldnt expect much.
