I have been speaking with REVO regarding the pending release of the switchable performance software for the B8 S4. It is very close to release, so close infact that it may be within the next week or two. I dont have any firm dates as of yet but i was wondering if anyone would be interested in a little trip to REVO for a mini meet and possible group buy and install? Just after number at the moment Here is a nice photo from REVO showing their commitment to getting things right for us. REVO intend on joining the forum in the next week or so, so watch this space and thanks for reading Phil.
