Personally, I'm not interested in making that kind of power out of my Mounty as it's a family vehicle; the KB would be much better off in the hands of an enthusiast building a rocketship!
Regarding tuning, most serious tuners I know, particularly tuning professionals, are using Quarterhorse and Tweecer units on Fords. I'm talking about forums like eectuning.org and efidynotuning.org. I retrofitted my '71 Mustang 351 with EEC-V from a late model Crown Vic, built the harnesses and everything, and use it to control the EFI, MSD, EDIS, and 4R70W transmission. EEC-V is completely tuneable, with almost every variable Ford incorporated exposed, but it does require a J3 port device like the QH or Tweecer. Having tuned the 4R in my Mustang for performance quite successfully, I'm really hoping to be able to "jack into" the EEC-V in the Mounty and make it more responsive.
As for the Bronco, I retrofitted the 400 with EEC-IV. EEC-IV is also fully exposed via QH and Tweecer, so I was able to turn the EDIS8 ignition on and retrofit that successfully. This has been a huge help when wading thru deep water crossings since the ignition is fully sealed and solid state, unlike a distributor. The sequential injection has really helped the fuel economy, but most importantly, it starts easy regardless of the altitude and temperature and it doesn't stall when rockcrawling. I rebuilt the motor using stock internals, but upgraded the rod bolts to ARP units, used improved oiling components, and bored it 0.030" over. A mild Crane cam and Cloyes timing chain really woke the 400 up - it generates up to 320 hp and 450 ft-lbs of torque at only 2000 RPM!
