I upgraded to the 85 mm BBK from a bored stock throttle body which was advertised as 84mm. I expected a slight improvement but the difference was a lot more than what I had expected. I got improved performance everywhere in the power band as well as slightly better gas mileage overall. I'm extremely happy with this product and I would highly recommend it.
