Not trying to make it worthy, just get it a little better then stock. After I get my new clutch thats probly gonna be it mechanically wise. As of right now with what ive done I get around 30mpg city so im very happy with what ive done so far. This chip should allow me another 1-2mpg more. Besides im getting a sportbike probly in february so im not gonna be spending a lot of money here.
