2018 Audi RS6 - Performance Tune
I am the owner of RS6 and Auto Upgrades Performace is providing performance Upgrades for me. At present, engine power has increased greatly, while oil temperature, water temperature, and engine performance remain stable. In particular, the sound of the engine is more pleasant than before, making people intoxicated.

2015 BMW I8 - Performance Tune
Lars took the time to explain in detail how tuning works and the process, as well as answering all my questions. The entire process was a breeze - in my case, I dropped off my vehicle and picked it up the next day.
Lars is highly experienced and passionate about his work - you could just tell by having a chat with him. I would recommend his services to anyone, especially to those who are into cars and want a higher/better performance on them. The transformation is real.
My car has transformed and I can feel the difference between before and after. It is now readily wanting to give more power, be more responsive, and provide better torque and power delivery.
Great work Lars!

2006 LS460L - Performance Tune
My car was tuned by AutoUpgrades, and I am pleased with their tune. My car definitely gained more power and torque. Lars managed to do pops and bangs tuning, and it changed the car's personality dramatically. It is faster and more aggressive than before.
I love his tuning, and it is why I am his repeat customer. Thank you so much for tuning my car. I highly recommend AutoUpgrades to anyone who is thinking of tuning their vehicle.

Positive: Professionalism, Punctuality, Quality, Value
Came for a slight tune on the Lexus but then received outstanding results, smoother driving, and the car just takes off now quicker than ever, Highly recommend it and will come back here for more tunes in the future.
Rahul Murthi – Goodwood Heights, Auckland
2008 Audi A3 - Performance and DSG Tune
Great service. Easy to deal with. Definitely recommend Auto Upgrades for anyone wanting a tune done. I had stage 1 and DSG tune done on my Audi A3.
Had an issue and called them up and they sorted it quickly and saved me a couple of hundred dollars (the issue wasn’t tune-related). No bullshit just straight up.
Highly recommend using Auto Upgrades.
Dan Ruttley – Half Moon Bay, Auckland
2014 Volkswagen Golf GTI - Performance Tune
It was great to discover how experienced Lars is in ECU tuning. He had a very no-nonsense, and very professional approach to getting the best out of my Mk7 Golf GTI without going over the top.
The results were amazing!... he turned my already great car into something much more top-shelf but without the price tag. Highly recommended.
Hamish Sansom – Mt Eden, Auckland
2007 Lexus IS350 - Performance Tune
Thank you again Lars for the amazing job you did on my Lexus IS350. The difference is really night and day with the few bolt-on upgrades which I had done.
Initially wasn't really expecting much with it being NA but to shave off .6s off the 0-100 is impressive.
Would highly recommend you to anyone who is looking at getting their car tuned!!
Daniel Holt-Pedersen – Mellons Bay, Auckland
2008 Volkswagen Golf GTI - Performance Tune and DSG Tune

2015 Fiat Ducato RV - Performance Tune
Auto Upgrades carried out a hp upgrade on my 2015 Fiat Ducato motor home. I am very happy with the increased power and fuel economy as a result of this process. I would recommend auto upgrades to any motor home owners wishing to carry out this process.

2016 Mercedes Benz Sprinter RV - Performance Tune
I recently purchased a 6 berth Mercedes Sprinter, diesel, 2nd hand with 200k on the clock. Good condition but was a bit underpowered which I found frustrating, especially on hills. Having owned a European diesel previously which I superchipped, I was aware of what could be done. Result: I approached Auto Upgrades. Great response from the beginning through to final delivery. On return the result was exactly what I was looking forward to, a substantial increase in HP and particularly in torque which allows a driveability that is enhanced at every level; from take off at lights to ease of traveling up hills. It's not speed that I was after, it was the change from lugging truck to driving like a car feel. In addition, I know from past experience an improvement in fuel consumption as the vehicle is no longer struggling like before. Totally recommend the change and the service Lars provided.
