Is there anything besides M flash that needs to be done to these cars? Both are MT Sport. Tell me before my dealer calls back! He just offered me $1,000+ below invoice on another car. I'm hoping he'll do the same on one of these.

 

Others here may have better info, but those are both pretty recent VINs and you may not need anything done to them. Do a search for a link to the TSBs (many threads) and check.
