2017 Mercedes GLC43 - Performance Tune
My AMG GLC 43 Mercedes has been an exciting car to drive, its acceleration was impressive when the throttle neared the floor, and in performance mode it was fast but "notchy" through the gear changes. For the performance car that is, I felt it was worth looking at cost effective options to improve . I came across Lars and Auto Upgrades whilst researching stage 1 tunes, ECU mapping, re-chipping and the like. Without knowing exactly how the magic is done I enlisted Lars to consider my (perhaps extensive) wish list of improvements and advise what was possible. In short, everything! The car has increased power and torque, the throttle and gear changes are assertive without being too sensitive across 4 driving modes and the sport + setting for high engine performance, really has transformed the car into a wolf in sheep's clothing. I had no wish to over tweak the performance just to improve power and smooth the throttle response across the rev range, which is exactly what Lars has delivered.
If you want your car to perform how you know it should, give him a call, you won't be disappointed.

2005 Nissan 350z - Performance Tune
My experience with Lars at Auto Upgrades Performance Tuning has been amazing! From the moment I contacted him, his professionalism and dedication to his craft were evident. Lars himself took the time to understand my specific requirements and provided valuable insights into how their tuning services could enhance my driving experience.
Lars meticulously fine-tuned my vehicle. The power delivery is smoother, and the overall driving dynamics were significantly improved. Not only did Lars enhance my car's performance, but he also provided outstanding customer service throughout the entire process. Nissan’s Hitachi ECU is annoying to tune, however he went the extra step to make sure the car was properly tuned and to his standards. He was responsive to any inquiries I had and kept me updated on the progress every step of the way. In conclusion, if you're looking to unlock the full potential of your vehicle and elevate your driving experience, Lars is the person to go to! His expertise, professionalism, and passion for performance make him the go-to choice. I can't recommend him highly enough!
Thank you!
