I installed unit on my 2014 Jeep Grand Cherokee 5.7L and noticed an immediate impact on throttle response, especially at 2000+ RPMs. I drove the vehicle for 15K miles prior to installation because I wanted to get a few miles on it so I could do an accurate comparison. I drove 800 highway miles last week and while I didn't notice any gas savings, I sure could pass the semi-trucks with ease! If you can pick this up for a good deal, do it!
