Xtremetuning

Took my A180 for a stage 1 ECU remap and am happy with the outcomeThe boys at xtremetuning know their job and are very professional at it.

I took my 2010 Lexus GS460 to Brno for a performance upgrade to the ECU, only for him to find that the chip upgrade had already been done in Japan prior to importation.He could have claimed that he had done the work as no one would have been any the wiser! However he is obviously an honest businessman as he waived any charge and advised me that the required work had already been done and there would be no charge. Rarely these days do you find such honesty and responsibility. I would recommend Brno highly to any other person requiring similar work from him.

I came to Xtremetuning after a failed ECU remap by another provider on my Sprinter Motorhome. That experience showed that remapping can go badly wrong if not done by experts. I'm very happy with the result which increased power by 50kW and torque by 110Nm - the van is now a pleasure to drive with better tractability around town and easy highway cruising

From the start I was struck by the friendliness and professionalism of Andrew and the team. Excellent information around the process and expected results were provided over email which gave me a high level of confidence in the outcome. On the day of my tune I drove my Audi TT down to Xtremetuning and was happy to be offered a ride to work saving me an Uber fare. At the end of the day I picked up my car and the tune was well explained. Unfortunately it was raining quite heavily so I didn't really get to test out the new power till a few days later, but when I did, I had a huge smile. I Highly recommend Xtremetuning.

Very pleased to have Andrew and Brno do their magic on my Fiat Abarth 1400 Turbo. The car was already pretty nippy but now the scorpion really has a sting in its tail. The throttle response is impressive, the power to weight ratio is insane. Thanks guys, highly recommended.

These guys remaped my mercedes A180 it turned the 1600 into a little rocket ship.Bruno and Andrew were so easy to deal with. I would recommend the service they provide to anyone. Thanks Xtremetuning

Brno just did a performance tune on my 2007 Bentley GT and what a difference. The car was not slow to start with , but now it is a completely different beast, upping the torque to almost 900nm.Couldn't be happier. Great guy great service thanks Brno

Brno is a top notch technician, and a real enthusiast.I tuned my 2011 Subaru Outback 3.6R, with the intention of increasing its torque and improving its dynamic range. I engaged XTG after weeks of searching (like many other potential clients) and found XTG had the best reputation, honest reviews and conservative promises, i.e. they didn't BS their claims.Brno contacted me in January 2020, but it wasn't until June 2020 that I pulled the pin and got the tune. Between their website and Brno's feedback, I was able to prepare my car (basic servicing + new consumables) for the best results. The tune took three hours on the dot producing far more gains than I anticipated.The EZ36D in New Zealand-market Outbacks puts out 191kW and 350Nm. With a basic service, a K&N High Flow air filter and running 95 octane (by Brno's recommendations) I got 213kW and 380Nm. The car's throttle response is vastly improved with the ability to now crawl, rather than dumping the revs. Its dynamic range is vastly improved with torque pulling earlier and longer throughout the power band. Cornering and city driving is finally enjoyable, and straights are a total highlight. Fuel consumption has also improved, something I'm attributing to the modified air fuel ratio parameters and improved throttle response.For a decade-old naturally aspirated vehicle, these are massive gains. While I've *only* gained approx. 30kW and 30Nm at the crank, I've gained a whole driving experience.I can't recommend these guys enough. Speaking from experience, their customer service is miles beyond the competition. They don't oversell their services, they give conservative estimates and treat all cars the same. Thanks to Brno and XTG.

Dealing with the team at Xtremetuning has been the best service experience I have had in years! They even came out my site within half a day of my initial contact. Not just super friendly, but Great communication. Brno was great at explaining the process in layman's terms. Also he turned my E63 amg s into an even more stupidly powerful piece of ridiculous engineering. I can now get from 0 to the speed limit at the same speed the government can spend money. MIND BLOWING.thanks team
