Computer performance programmer

Has anyone installed and seen results from any computer reprogrammer or chips for their Jeep? MPG increase, power increase? Or are these a waste of time and money?

Great for most cars, pointless on the 4.0. The engine wasn't built for power, it was built for maximum torque output and reliability, and reliable they are.
