Considering a remap for the A7 BiTdi and I understand these cars are pretty nice to tweak to improve the overall drive. I've contacted a few places and narrowed it down to either EcoTune or Revo - on speaking to both its roughly similar end results however I'm slightly surprised that Revo have advised it will be a 30mins job as no Rolling Road would be used..........therefore seems its simply just a standard file download and out you go. EcoTune will be 2 hours as they will set the map up specifically for your car and get print outs before and after. Pretty surprised Revo advise no rolling road used to check the mapping through the full rev range on your car but must be the amount they have done they are confident this file is best fit Anyone used either company recently - experiences? My mind is currently on the EcoTune option but always interested in others views as new to Audi (Subaru / Jaguar / BMW previously). Thanks.
