Saw over on the Vortex that APR has vastly reduced the price of their RS6 tune. From what I saw most thought it was a bad value when it was around 2k, but how about now, worthwhile at that price? Per the blurb on their page that price also includes the TCU tune but still need to ante up the extra bill if you want program switching.
Still have one or two items in queue to address before I look into a tune, but now that the price is way down and have a local vendor I might go this route sometime next year.
