Wow, no more throttle lag in my Jeep Grand Cherokee Limited 2014. While it doesn't give you more HP, it feels like a new engine. I was really surprised at the increase in response. Really happy with purchsae

Read that works best if used with premium fuel, have ran premium in it the whole time I've owned my jeep. It does actually work as advertised. More power across entire RPM range, has increased my mpg by only 2 though nut still an improvement.
