Which of these 3 should I be ordering?

G12: http://www.ecstuning.com/Audi-B6_A4-...ling/ES465357/

G12 Plus: http://www.ecstuning.com/Audi-B6_A4-...ling/ES259379/

G12 Plus Plus: http://www.ecstuning.com/Audi-B6_A4-...ooling/ES5652/

They all seem to have the same description, so I'm at a loss as to what the difference is. If someone could enlighten me, I'd really appreciate it.

 

G12++ is the latest and I do believe they all mix together..

 

I kinda figured that'd be the answer, but it seemed like a good idea to confirm before purchasing. Thanks for the info.
