Amazing difference!Professionalism, communication and a wealth of knowledge - not to mention, a genuine heck of a nice guy! I felt very safe leaving my car in the hands of Tune technic. Magic was worked.thoroughly recommend. AMAZING!!

I got exactly what I needed, extra power in the 70-120kph range. Car is smoother and still the same amazing fuel economy. I was thinking of changing cars until I got David to do the retune. A very worthwhile investment and great service.

Great tune, now pulls like a train, accelerates uphill like you would notbelieve. Better than my Audi S3, and a very good service from David.

Fabulous, love driving my "mum" car. Nice to be able to put your foot down and move if you need to.

very happy with my new tune. car has a lot more mid range power and the increase torque is great. customer service was top notch. no complaints at all! i recommend to everyone that asks about my car! Thanks David when i trade up i'll be back!

What a difference – it now drives like a rocket and we will keep the van as it has years of life left in it. Thanks for your great work in figuring out how to improve the performance, we don’t need to pull over on the hills and let trucks pass any more

I would like to thank you for the excellent job you did setting up the launch control on the Supra. I raced at the Hampton Downs Powercruise Off Street Drags on Sunday and I won the event. The car was leaving everything else for dead on the line (4WD Evo’s and Skylines and also the V8s) and no-one even came close to me in the racing as a result of the quick launch. Well done.

Every time I get a new car I take it to David, and every time I am blown away by the improvements. My already-zippy Golf GTI is now a stealth race car! As smooth as always, but plenty more power and plenty more torque. David always tunes my cars within safe operating tolerances, so I know I can confidently drive it however I like, without putting my engine or drive train at risk. Don't think about asking David to tune your car; just do it!

Thanks for ecu upgrade on my golf gti.Since then my car has been running smooth as, with extra power when needed, i dragged off another gti last week he had no chance lol, also quite good on fuel, thanks once again.

I refer to the addition of a ECU unit on the above vehicle on 9th July 2015.The standard specifications of the vehicle is Stock Power/torque rating 88KW 160 nm.The tuned power with the addition of the ECU resulted a upgrade to 99KW 180 torqueI found the benefits to be a major transformation in engine response and the acceleration through the gears. The results exceeded my expectations and made the vehicle more fun to drive. I would recommend the addition to add to your car driving experience, money well spent.

Just drove car back from Auckland to Kerikeri, goes great very pleased, heaps of good passing power. pretty quick from 80 to 130 – 140km

Really pleased with the improved performance, I find the engine response to be better than the d4d hilux. Economy seems about the same which was fine to begin with.

The RS3 is going well. FYI I tested the fuel consumption on a long drive to Langs Beach and back on the weekend. Same driving style both ways, light throttle driving at the speed limit, no rapid acceleration. One way on the Audi factory ECU map and the other way on your ECU map. Your map fuel consumption was 6% less.

We are very pleased with the way the car drives. It's quite a transformation. The torque seems to be there all the time and you can feel the extra power at the top end. It seems to run cooler and sounds nicer too. Good job! How do you do it?

The van pulls much stronger now, and drivability through the gears is much smoother with the additional torque. It pulls so easily, with far less need to leverage the RPMs to coax it along. Many thanks!
