No, its not something already done in the PCM.

BTW, overkill PCM's rock...in terms of a pretuned PCM.

Basically, you get your new PCM in, follow the instructions as per removing the old PCM/Installing the new PCM.
Then you'll drive around for a bit, and take the car to a dealership..and tell them you need a CASE learn performed. (it basically helps the computer figure out the tolerances from the Crankshaft position sensor)

Just tell them DO NOT FLASH THE PCM, otherwise, you'll have another stock PCM.
