Today, we put Chicken's First Edition Bronco 2.7L, that we installed the JB4 on in a previous video, on the dyno and made impressive numbers, with JUST A TUNER. This truck was totally stock but now, has woken up with the power of the JB4. With this simple bolt on, your truck can go from no show to ALL GO!

If you have any questions, don't hesitate to reach out to us!
