I just completed a 2500km road trip through New England with a freshly built 2.2 wbx that has rocky jennings stage 2 heads and the Mansispeed EFI along with his injectors and 1.35 ratio rockers.

The whole package worked out so well.

For 60mph highway driving, I was getting about 20 mpg which I felt was pretty good.

Throttle response is superb. Never had a single hiccup, hesitation, issue at all. It started up every time after a few cranks. The components are all easily sourced and replaced if needed in the future.

I am very happy with the Mansispeed EFI.
