Do JET performance chips work?

Does anyone know if JET performance chips work and are they worth the money? I have a 2004 RAM 1500 quadcab with 5.7L Hemi with A/T. I purchased a programmer III plug in tuner and it did not really do anything for the performance.

Bought 1 for my 02 Dakota 4.7 auto. Made 2 dyno pulls ( my freind has a portable dyno he takes to car shows so some guys can have bragging rights)

The Jet chip I had (stage 1) was in series with the comp. and while it provided initial gains based on laptop dyno software eventually the gains went away as the internal comp compensated for the chip.
