They did indeed, i've driven the car for the past few days with the AC on and no throttle lag on my end so far.

Thank you for the information.

Posted in a different thread, but wanted to post here as well:

I also was having the issues addressed above. They really soured me on the car, and I had considered selling it on multiple occasions.

I just picked my car up from the Dealership after having SIB 12 15 14 performed along with the adaptation resets and holy shit....

I was so skeptical, but I'm a believer now. The car drives 10X better. Even just auto mode commuting for fuel economy is much better. The 1-2 shift (which was a little jerky before) is unnoticeable now, and the throttle lag during rolling stops is completely gone.

No more idle issues and jerkiness when the AC is on either. I drove it home yesterday and sat in traffic due to an accident and it creeped right along without a single stutter or lurch. Looking back, I drove so carefully as to not upset the car, but that is completely gone. It now drives just like any other normal TC automatic, super smooth.

Truly a night and day difference.

I just got my car back from finally having SI B12 15 14 done. Didn’t fix it at all. So, so frustrated.

Just had the update and resets done and damn!!!
I WANT to drive my car now. It got so bad that I didn't want to drive the car in traffic or in town driving. But car drives perfectly now. Or maybe more accurately, drives like it should.
One gripe, to me, I don't see why we have to pay for what is obviously a software glitch.
But at the end of the day, I'm satisfied.
