GM is not doing anything uncommon...All production EPA approved vehicles factory tune in this manner.

And get over the turd comment. You guys keep bringing it up after I admitted/apolgized it was off base quite some time ago. Jeese....

So from the way I understand it, you are saying that you are picking from pre-built maps based on how the customer responds to some questions.

So there is no custom tuning being performed and these are all base/canned maps assembled togther into one load.

You see, at least when I do it from Harley customers I have them a data recording and send me their data file first so they are actually getting a custom tune and not something I assembled from some questions they answered. I have them do this before and after file creation to ensure the knowck sensor does not get activated (something you will never know without ECM data file recordings)

You answered my question. Thank you very much!
