Today, we test out the JB4 Tuning Device on our 2022 Ford Bronco Raptor on the dyno at Palm Beach Dyno. We take the Raptor from Map 0, which take it back to stock, and test all the way through Map 5!

Just like our First Edition 2.7L Bronco, We got some serious increases to the wheel! Overall, we couldn't be more impressed with the JB4's ability and safety.
