I also saw the one in the link below. It claims to also increase the rev limiter/remove speed governor/reduce gas pedal lag. Not sure if either one of the two previously mentioned also do this but hp/torque aside, I'd really be interested in reducing the lag. I think these "tunes" require either for the ECU to be sent in which means no Treg in the meantime, or travel to the nearest dealer/shop that can flash the ECU in car. Personally I have no time for either one. the $$$ is not even a factor.

I work in the same complex as Unitronic, i will have my VR6 Touareg (2011) tuned in the next couple week.
If you buy the tune from them you can also buy the Uniconnect cable, which will allow you to install the tune yourself, or revert back to stock when needed.
The uniconnect also can be used as diagnostic tool.
They are real car guys, real VW/Audi/Porsche fans. They are extremely well known in the Province of Quebec, even in Eastern Canada.
They are official partners of Audi Club of Canada. They are present at every local event, active on social media and local forums.
I had multiple cars tuned by them in the past 10 years (B5 A4 1.8T, B7 A4 2.0T, B8 S4 ).
Earlier this summer they had this badass R50.
