Great performance boost!
I installed this on my '14 Jeep Grand Cherokee with the 3.6L V6. When driving in the normal ECON mode, there was a big lull in the power between 1st and 2nd gear. Even when trying to accelerate to get on the freeway, I almost always had to put it in Sport mode to get the power I needed. Now, the power lull is gone and there is always enough power on tap. Also, it now makes a lower pitched "growl" where before it had a higher pitched whine. Easy to install and I love my car so much more now!
