Worth every penny. Still early in the drive testing as I’ve been out of town on business and just installed. Very satisfied with the initial change in power and acceleration with the slightest of touch on the gas peddle using the ECU stock flash. EXCELLENT! Thank you AMR Performance for the detailed insight when I initially called. Second to none in customer service.

I now need to constantly watch my speedometer since the acceleration is on another level after doing the stage 1 tune… I had own my car for a year already so got really comfortable with it in all situations, now I’m re-learning how the car drives and loving every minute of it

First of all, excellent customer service, installation is flawless and simple instructions are easy to follow.
Now the details – 2022 GLC43 AMG
Before the tune I ran 10 GPS race times for 0-60mph and 1/4 mile deleting the fastest and slowest runs to get a base line of the remaining 8 runs. Jan 18, 24 Conditions are cold 37° single lane highway on All Season tires.
Stock 0-60mph=4.9sec avg, 1/4 mile 13.5sec avg across 8 runs.
With AMR stage 1 0-60mph =4.6sec avg, 1/4 mile 13.0sec avg across 8 runs
the pull was noticeably better and the exhaust pops are much more frequent and louder. the AMG stats showed 337hp before, and now best run had 386hp on the display.
Overall I am pleased with the install and hat tip to AMR Performance for opening up the V6 Biturbo

Chris Chan is the man you need to talk to if you’re considering the AMR tune. He is extremely helpful and available to answer your questions and help you through the process. I couldn’t be happier with the service he provides and the tune itself. Much needed improvement to my 2022 GLC43 AMG

I got the ECU and TCU tune for my 2021 AMG GLC 43 and could not be happier with the results. The support team was super helpful getting me setup with the flashing/logging software so I could tune and log data via the ODB2.

I just want to give a huge shout out to Matt and the entire AMR Performance team. I could not be happier with the tune I got for my 2017 GLC43. My girl is now a complete beast! Matt’s customer service was top notch from start to finish.

Working with AMR has been amazing experience. Excellent service and product. I absolutely love the tune on my Mercedes GLC 43. Transformed the driving experience!
