I am very impressed with the performance increase. I have noticed a 10 to 20% increase in MPG as well, in normal driving. Only one strange thing happening and that is my radio wants to change to a non-receptive stations by it's self from time to time. It is happening less often as time goes on and I am going to wait a little longer before calling customer service. It may help to pull radio fuse but I will call before wasting the time.
