Any of our European friends with C7 RS6 Avant's yet who plan to MTM-tune their car's? I got a newsletter e-mail from MTM today that said Mayer has tweaked the C7 RS6 Avant (and presumably will to the RS7 which we are getting in the USA) up to 722HP/885Nm(653lb-ft), up from their tune posted on their website at 685HP/865Nm(638lb-ft). They say the 722/865 version is good for 0-100kph in 3.3s, 0-200kph in 11.3s, 0-250kph in < 19s, and a top speed of 340kph/211mph. And reportedly, he is working on further upgrades from there.
Will be interested to hear/see some MTM-tuned C7 RS6/RS7's on the forum.
