North american 2.0 TDI 140 ECU reflash??

Since this engine's been available for more than a year now in North America, I was wondering if any ECU tuning company came out with a reflash for it.
I know REVO does one for the europeen TDI140 engine but nothing on their website for North America.

I think Evotech has it as well.

Thanks, I'll check it out.
