So this is my first youtube vid, so forgive me if it isn't the best. I did two cold starts, and I also shot a before and after vid of the install, all in one video. It revs and accelerates cleaner/ smoother. After having it on the truck, I noticed a consistent 1-3MPG increase in both city/highway. This truck by NO means is efficient and the best I got on strictly highway usage was around 18.5 mpg. Did help with normal acceleration as well.
