Thus far I am very, very happy with the 57's performance in my 2003 Jeep Grand Cherokee. Though I've only had it installed for about one week I have noticed the pick-up response when accelerating. The true test will be in the coming months, when I hook up my 21 ft. vintage HR Aluma-Lite travel trailer and head for the Sierra Nevada to do some long need fly fishing. Thanks Auto Anything!!
Good Product for the Ecodiesel
The install was very straight forward and easy. Everything that I needed was provided. It finally makes it sound like a turbo diesel. The spooling up now sounds incredible. I have not noticed much gain in MPG's, but I have been towing a bit more than before. I don't feel any power improvements either. I also have a GDE tune so I believe if it is paired with an exhaust it would help.
