: New emissions reflash?

12-05-06, 08:45 PM
Anyone aware of the good/bad for the emissions reflash for the 05 CTS-V?

12598975 0000DB78 - New calibration to ensure proper catalyst monitoring at idle.

To Flash or Not Flash, that is the question....

It is up to you to you.. Wheather or not to have it done.. Probably can't hurt to get the latest firmware flashed into the PCM, especialy if you got a recall notice. If you are planning on having your "V" tuned for better performance via PCM. Make sure you do the recall flash first. :)

How much better performance can be had with any tuning? Who do you recommend?
