I don't notice additional horse power but I see the idle and rpms stay at a more consistent rate. Example is when you let off the gas petal it takes a few seconds before the RPms drop. In many cases I have to brake more often or give myself a longer distance to stop/ slow down. I see how this saves on gas. I feel it was a good investment for a car.
