Well worth the money. Quicker response feeling on throttle. Deep growling sound when stepping on it. "Boss said the sound reminds him of the old 4 Barrel Carb days" Can't say anything about gas mileage, because I can't keep my foot out of it right now. Easy install and great directions. Plus, I love Autoanything return policy of 90 days if you don't like it.
