Default Suspension update
I took my Z for its first oil change yesterday and I was told that I needed a suspension recalibration update. Anyone know what this update might be?
The Tech Bulletin is: N232399470. Incorrect Suspension Calibration. They reprogrammed the suspension control module.

Is their a way to know what your calibration is without going to the dealer?

Shouldn't us Z06 owners get a letter in the mail or something from GM? This is the first Ive heard we needed a suspension recalibration upgrade. I did my oil change in September and the dealership didnt say anything about it.

Its a tech bulletin - not a recall or even a TSB, so nothing in the mail unfortunately!

It says recall on the receipt paperwork. The service rep said that he just received it this past week.
