    Bought the Hewitt bypass kit (plug and play). Works great. Take that Toyota.

    Very nice.

    Hewitt doesn't offer a kit for the 5.7 Flex Fuel.

    Is this because a the Flex Fuel doesn't need the bypass, or is something else going on?

    Thanks.

    This is pure speculation on my part. Since the bypass kit plugs into the throttle body there could be a programming issue with the O2 sensor that they have not addressed yet. Have you spoken to the technicians at Hewitt? Very nice folks. If you haven't I would give them a call
