Jason F from AMARILLO, TX said, "Amazing product my car is much more responsive the power increase is great. It has made it much more fun to drive and as others say if I could stay away from giving it as much gas the mpg savings is nice. Even driving as I normally would and pushing it some I've seen a better average mpg per tank of gas."
