One thing I've always found very attractive about using an OE PCM is the fact they have the ability to store trouble codes & freeze frame data.. If something is wrong you know where to look, no aftermarket PCM that I'm aware of has that capability... The GM LS PCM has the ability to control the transmission, fans, traction control, boost control... All can be switched on or off within the program.... GM gave the programmer the ability to control everything from a mild daily driver to a very serious race package.... To bad Chrysler doesn't do stuff like that...
