Do you anticipate any improvement with the EFI?
Not sure, but think the preformance and mileage will be a lot better with EFI.
Do you know what's the difference in the version? besides the price difference?
Wasn't aware there was a price difference.
I compared the pictures of the kit on the Fast web site verses Amazon and Summit.
Next, called customer support and was told the newer release was different in both firmware and some of the components.
Specifically I don't know the exact differences, but thought since I was buying, would get the latest and greatest.
