I checked with my dealer in Calgary and was quoted $300 then they called and said it was $550 and $300 was just the GM part not including their labor so I gave it a pass and will get it done in the USA for $350 total. I was told by the tech that does the upgrade that you can specify what you want done. Upgrade tour, sport and track or just one of them. Price was the same regardless so you're better off getting all of the modes done. They also said the vehicle needs to sit overnight at their location to allow all the settings to "take". Other forums indicate you can take it home and let it sit overnight.
