My buddy just put that Ford tune in his 2.3 Ranger, and he says it's night and day better. I'd never even heard of it...Explains everything!! My Ranger was awful until I installed the Ford tune. It made shift pattern different and made a not very good shift pattern great! Hopefully the Ford performance tune that comes out this fall would do the same for your Bronco. The added hp and torque seemed to help the vehicle not shift for gears as much too!!
Definitely worth trying, once it's out.
