My experience with XRT has been amazing.
At first, I had a stage 1 OTS cobb tune and loved it. That opened the car up to what it was capable of and once I realized that, I got hungry for more. I saw a post about XRT and started to get incredibly curious on all the gains someone received from them. Once I emailed XRT(Ed), he informed me BlackBerry Messenger(BBM) is how he chats with all his clients. He is based in the Barbados so we can call each other on BBM or Whatsapp to avoid oversea charges. After tons of research and seeing no other tuner is pushing out that type of gain with my mods, I sold my AP3, and was ready to start.
Ed informed me to download Team Viewer so he could remote into my machine and download all the applications needed to setup the logging parameters and created the file structure for logs and roms. Even if you are not a newb to open source tuning, LET HIM SET IT UP. It will be easier for everyone and if there are any issues, he is perfectly capable of correcting them.
Once all the preliminary stuff was done, he sent me a version zero rom to show me that my car is capable of a lot with stock boost. My jaw dropped. Throttle response was insane, the torque was there, and you can clearly feel that the car enjoyed it much more than the Cobb OTS tune.
As the process continued, you could feel the car run better and better as the days went on. He transformed my car so much, I would rather drive my car to work, Downtown Washington DC, than take the train. I feel like a little kid every time I hit boost now.
With XRT, they could get maps out same day or next day. Ed is very good with being responsive within a few hours and letting you know if you need to check something on your car or not. He is very particular about how he tunes a car and how it is running. Making sure your car is mechanically fine is key to having a smooth and successful tuning process. Overall, he is a skilled and very knowledgeable tuner. He changed my car from a slow non- responsive 2011 LGT into a responsive torque monster that I enjoy driving every single day. Boost comes on smooth, the car moves when I tap the gas and everything on the car feels great. It took about eight to nine revisions before the car got where it needed to be. He is done with my Subaru for now, but he will be doing my GF’s 100% STOCK CVT Crosstrek and I am sure I will see major improvements there! I attached a Dyno sheet along with Ed’s Virtual dyno of the same dyno pulls.

From time to time, I do get questions referencing XRT. So let me take some time to answer them.
XRT does not adhere to today’s trend in tuning that is growing worldwide where attaining the customer money is key and providing great service takes second place. We believe the service we provided is important and is second to none.
Q: What makes XRT different to others?
A: XRT core interest, passion and precision is what makes that difference. To achieve a thumbs up from its customers or a thank you is its aim. XRT prides itself in not giving up in the most difficult situations or say it cannot be done. We let our work speaks for itself. We just love to take what is given to us and optimise it. Our main focus is giving that SUPERB Experience to the customer, leaving a permanent smile on their face.
Q: Why does XRT costs a little more when compare to other ETunes?
A: XRT does not distinguish the difference between Etuning & local tuning as others do. We believe in given the customers the best quality of service, time and support. This is attest by our valued customers. XRT believes in full customised tuning, even to be there online through the process by the use of remote software like Teamviewer for Live Tuning. We do not offer off the shelf maps with minor tweets or one rom for all cars with the same ECU ID. We also believe in fine tuning to suit your car configuration and your needs. We brought this process over from working with EMS and with customers who race their daily driven cars. Please see our tuning strategy below that makes this all happen….ingrained in out DNA.
Q: What is XRT support service(s) and why is it different to others?
A: We give close to 24hrs of support through Teamviewer, Email, Whatsapp, BBM and BBM Group. Support is fast and reliable. Customers are welcome to even call. In all reviews, XRT is praised for this. It is above standard when compare to the tuning/tuner industries. We provide and request constant feedback from the customer and revisions of roms to reach optimum performance.![]()

Q: What makes your Transmission tuning different to others?
A: XRT takes the time to develop Transmission tuning based on feedback and countless customer reviews to make that difference. In addition, due to feedback, support is given to make changes to suit the car and the customer.
Q: What other services do XRT offer?
A: XRT collaborates with its customers for troubleshooting and diagnostics through data logging and reviews. XRT also offer support for upgrades, even Project Management Services. ![]()
Q: If my ECU is not defined or a definition is not available, can you support it?
A: Yes. we create our own definitions for full support, even able to offer better support as a tuner compare to other tuners using Cobbs, Ecutek, etc. We offer a more reliable and safe tune. This is attest by some of our customers who have replaced their Cobbs or existing tuners who used Ecutek to tune their projects and not getting the correct, safe and reliable results.
Q: Do you tune turbo cars?
A: Yes, we do. XRT was born out of WRX/STI tuning. Actually more STI tunes that any other model pre XRT founding. We have work on projects up to 600HP and consulted up to 1000HP.
