After installing in my 2004 jeep rubicon. I noticed more power right away and my auto tran shifts smoother.before the install when cruse control was set to 55. some hills would make the tran shift into 2nd gear and rapping the motor up to 4500 rpm.After installing the chip it goes over in 4th and only shifts into 3rd if it needs too. I would not go back to factory. Great product.
