Auto Upgrades Performance Tuning

I took my 2016 Renault Clio for Lars to tune. The car is now running a lot smoother and more responsive. It is well worth it and his price is very reasonable. Lars has extensive knowledge about car tuning and very friendly. The moment I spoke to him, I knew my car will be in good hand.I had another car also had issue with the ECU, he took a look at it without any hesitation and solved the issue, Both of my cars now run perfectly.Lars is the guy to go to if you want to get your car tune. Highly recommended and extremely reliable service! Thank you Lars!

Lars is probably the easiest, smartest and a very professional guy to deal with. He tuned my ISF and I have to say it Is definitely more snappier then before. He explained to me and showed me how he went about doing the ECU tune and also showed me how much HP and NM my car should have made and what he estimates it to be. He also explained the reason for not running dyno testing and how it is not as accurate as people think it is and is also a high risk of damaging my vehicle.I definitely recommend using Lars as it is a lot of Value for the money spent.

Just a quick note of thanks to Lars. The performance tune to my 124 spider’s made it very nice to drive with a good “pull” through range of gears now. If it had had a fault previously it was drop off at high revs which I don't notice as much now. Also it is still “understated” and I am surprised she’s still super economical when plodding in traffic in 6th. Well done, thanks again.

I have taken my LS460L for pops and bangs tuning. Lars has a deep understanding of vehicle tuning, and I am satisfied with his excellent customer service skills and the fantastic products he offers. After his tuning, my car gained more peak torque and power simultaneously, and it pops and bangs around 5000rpm. Who would think of a boat to do pops and bangs? This is just fabulous, and I highly recommend him!!

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. (My tune was done a couple of months ago, but Lars reached out asking me to submit a Google review... I see he must have done this with several of his customers, and it's a tribute to his service given how many have taken the time to submit a review in the last few days!)

Had a tune done on my amarok and Lars even managed some minor mechanical mods. Result, more power Smoother through the gears and much more pleasant to drive. Cheers mate.

Lars was very helpful and knowledgeable in explaining the entire tuning process, I would recommend to anyone looking to get a tune done on their vehicle.

When your car is not the cheapest but yet you still have some pace wishes, you have to be sure about who you trust to unlock the power of your precious car. I know from experience that a lot can go wrong with an upgrade. When it comes to my BMW X5, I only trust Auto Upgrade. After Lars intervention my car become a pure joy to drive. It reacts so swiftly, more power, a perfectly well balanced car. I used to drive my BMW X5 in sport mode to come closer to my expectations but after the upgrade I feel no need any more to drive this baby on sport mode. I’m very happy with the performance of Auto Upgrade and I can’t recommande them enough. Very professional and reliable Lars truly have under contrôle the fine details that will make the difference in your driving experience.I literally thank you every time I start my car!

I found Lars to be very knowledgeable and very easy to talk to. Very good experience. My car is amazing now that it's been tuned by the way.
