MattS 600whp+ 2005 USDM STI 2.5 6MT

Matt came to me on his last hope in getting his long awaiting 2005 STI tuned, after his attempts to do it himself. I believe he did a fantastic job, but a professional hand was needed for his final push pass 25psi. Uncertain with his build (operating with issues and testing over a long period of time by him,) we offer inspiration that we can achieve results, even if it is short glory – because we can show it can be done and it was DONE!!! And in 3RD Gear. That was our achievement. In 4th gear, he is well over 600whp.

It was our first time working with the MerpMod Patch, which was nothing different to the Carberry Group N rom in a sense, but it was still interesting to see that setup outside of Cobb Tuning for a 32bit ECU Car.

I am looking forward to the future where we use the ETS FMIC and a few other minor changes like 272/280 cams.

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!

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 – https://chat.whatsapp.com/E1dPtXGgn3oEJAEm6P3aeU
