The all-new Ford Bronco boasts a lot of potential! This 2021 two-door Cactus Gray Bronco is pretty quick considering the purpose of the vehicle. Yes, we know the Bronco isn't supposed to be quick and dynoing one of these seems rather silly. However, it's what we do here at LMR! We enjoy doing this to provide value to our customers and viewers.

The Ford Performance Pro-Cal tuner gave it the extra "oomph" it needed. The Ford engineers improved the throttle response and remapped several other parameters to allow great peak and curve gains. Another great feature of the Pro-Cal tune is the optimized shifting from the 10R60 10-speed automatic transmission. The shifts feel more precise and "crispy" when driving normally and under wide-open-throttle.
