Lars did a great job of tuning my GTS... passionate and very helpful!
Lars was very professional, the tuning result was outstanding. I’m very happy with it.
Having used Lars’ service a couple of times. He is knowledgeable, efficient, trustworthy.
Thank you for the tune! The difference in throttle response is amazing and the engine has come alive. My S8 has transformed.
I would highly recommend to anyone who wants to open up the potential of their vehicle.
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.
WOW this is amazing, thanks muchly for tuning my car the power is different.
I can see and feel how much power it has gained. It's like hard to control the speed LOL.
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 a 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 repeating customer. Thank you so much for tuning my car. I highly recommend AutoUpgrades to anyone who is thinking of tuning their vehicle.
Brought my Subaru Legacy to Lars to have an ECU tune. My car runs better and it became fuel efficient as well.
Definitely recommended Lars to have your car tuned as well. Thanks Lars
Very genuine guy and amazing service. Looked everywhere for someone to tune my car but had no luck until I came across AutoUpgrades.
Gave it his best and the car does everything I want, 100% satisfied.
More responsive, a bunch more torque and using less fuel - cant ask for more than that!
Thanks for the tune Lars!
Performance ECU and Transmission tune from Lars. Knowledgeable, helpful, and professional.
Car goes really well, sounds better, and fuel bill is even down. Recommend.
