What it does is remap the timing and fuel curves in your ECU to increase performance. It's not really a scam but more of a waste of money. $400 for 20 horse power?!?! Lame.

Money that can be better spent on other areas of the Jeep.

There is a lot more to it than just swapping out the chip. The upgrade chip will also change the operating characteristics of your engine. The biggest example of this is that the engine will run much hotter than normal so you also have to upgrade your thermostat and water pump. I found this out the hard way with my GC 5.9 Limited when it caused the head gasket to blow.
