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.

I am working on a 500+whp Block Dom 5.0 2004 USDM STI that is having some problems when the boost is over 22+psi. The customer created this short video for me to hear what it is. But I cannot resist in enjoying how sweet it sounds.

PaulH – 2011 JDM Subaru Impreza WRX STI A-Line 2.5 5EAT

Reviews:-

Car feels amazing during pulls and can’t wait to get it on a nice stretch of road

The car is now feeling much better than I imagine, it moves and feels GREAT threw out the entire power-band, no more waiting till after 5000rpms to feel being pushed back in the seat. XRT is the best in customer service, turn around time and great advisor and tuner. Turn the car from slouchy to speedy

Its now tuned 🙂

Please read my review about XRT. I recommend XRT for all you needing a perfect tune.

This car is from what I know the only one in Europe at this time. Only made in 401 pcs year 2002.
As this engine is a hand built STI engine for minimum 100 octane is was very important to get it tuned for swedish 98 octane and also some improvement.
I have been following openecu forums since 2007 and ONE guy have always stand out in lots of posts. Mr. Edward!
So when car was ordered I contacted Ed and asked if could help me tune the car.
When the car was road legal we started the tune.

The support from Ed is totally outstanding. He responds to question almost 24 hours a day. He send me new updated roms faster than I could flash and log. His commitment is unique. He is more than a tuner, he is also a friend and a listener. Think that is extremely unique. He care about you and the car!

Off course the tune is also outstanding. The car is now starting more easily, idle more smooth, better respond, better engine sound, more power low and high. This tune is what Subaru should have done. Very Impressive. I can recommend all you that need a real good tune XRT and Mr. Edward.
