Finished up installation last week and after a week of driving I can comment on a few things. First off I don't really see much if any fuel mileage improvement. Not really disappointed because I wasn't expecting a miracle pill here. What I do like though is the throttle response the car has now. Much quicker. Also I travel to the Sierra Mtn's regularly and I can really see the difference in climbing hills. Overall happy with it.
