diablo preditor

  1. Changing A6 shift points with Diablo Preditor??

    C6 Tech & Performance
    How much flexibility does the Diablo hand held tuner have with changing shift points in a A6 transmission?
  2. Pro tune or Diablo Preditor??

    C6 Scan & Tune
    Getting a pro tune is nearly $500 bucks every time. Can a Diablo Preditor do what a pro tune can do? I have a 2007 A6. Thinking about it, it just seems that the Preditor is the better economic decision?
