Does anyone know of a good company that has aftermarket modified ECU or ECU piggyback chips for Ford vehicles? Chike, maybe???

My dad has a 2002 Ford Ranger - SOHC 4.0 liter V6. I was hoping to help him get an aftermarket chip for some more power (and possibly remove the electronic governor, as well). This thing only puts out about 210hp and 240ft/lbs, which IMHO isn't enough for 4.0 liters. It is also governed at 90mph.

If it works out well, he would like to see if a similar chip would be available for my mom's 1989 Ford Bronco 5.0 liter.
