Subaru Ascent Tuning

XRT is the only Tuning company beside Cobb Tuning to demonstrate it tuning capabilities and the release of tuning information to the World before any other tuning companies. In fact, tuning companies requires Cobb Tuning to support these models. XRT don’t! Thats being innovative and creative!

Please also note XRT is a Cobb Protuner and we support tuning of the Subaru Ascent using the Cobb Accessport.

In respect to our research and development (as shown at the very below) on the Subaru Ascent & the FA24DIT operating in this vehicle, we are offering Stage 0 and 1 tuning support to owners with the following requirements:

  • Tuning that does not require a device to be installed in the car
  • Improve driveability with clear objectivity in engine response
  • Improve Fuel Mileage
  • Reduce throttle lag
  • Better sounding throaty engine
  • A little more pep (Stage 1)
  • Improve CVT Operations

The tuning is really considered for those not liking the small little issues as highlighted in our XRT Subaru Ascent Whatsapp group –

    Both of your distance tests say Attempt #1. Was this just a mistake? Or do you have another set of numbers coming?

      Not it is the software way of saying that in the testing, it was one scenario instead of multiples in one session.

    Just bought my wife a 2020 Ascent Touring and came from a diesel x5 and the Subaru is a turtle , is there anything I can do to make it faster without voiding the warranty?
