  1. JeremyS –

    Very happy with the response my truck has had from the tuner. 5star also very quick to respond with any issues I had with calibration.

  2. AlexL –

    I have a 2002 F-150 with the 4.6l V8, and this tuner has saved me about 7mpg when its on Economy Tune.

  3. SkidA –

    Best tuner I’ve had so far. 5star really knows ford vehicles. Really woke up the trans with faster shifting between gears and shift points.

  4. Rob778 –

    This is insane truck is a rocket ship I have stage 2 and 3 race cars and on a drag trucks gone when uhit 3rd to 4th well after that ur sailing, I’m couldn’t be happier it’s been a month and my hair still stands up.

  8. RaginRoostr –

    A great pair to work with, the tunes are great and the tuner is well programmed. Changing between custom tunes is easy. I tow a heavy boat and change tunes from performance to tow and back. The SCT x4 makes that easy.

  9. Viking8466 –
