2012 Genesis tcm update

[2009genesis4.6]

Have any of you guys had your tcm updated on your r specs? If so did it help shift points etc? I had a 4.6 and after I got the tcm updated my shift point where much better. That car did not lag as much and would up shift sooner. I'm thinking of calling the dealer to get my car checked out for any recalls that may still need to get done. With my 4.6 I had to pay for the tcm update, I found that really stupid.

My R-spec is still box stock and I've had no issues with shift points. The only thing re: the transmission I find odd is when backing it seems to need more gas than starting out forward. It isn't as sensitive to engine RPM's in reverse as in forward gears.
