MB C43 AMG (w205) RV3.1 ECU Software Upgrade (SHIP IN ECU)

Awesome tune, great customer service and communication! My ECU was flashed and returned to me within 24 hours. Couldn't be happier!

Purchased RV3.1 for my C43 AMG. Quite pleased. Chris Chan has been a pleasure to deal with answering all my questions before, during and after the transaction. I used to drive in Sport mode for my Individual setting, now Comfort mode feels like Sport+ This thing is a rocket. Yet to put it through the paces, but I couldn't be happier. Even idles smoother, can't even tell it's on.

Wow. The entire AMR team is great and dang, do they know the C43/M276 platform well! Chris (Instagram: C_Chan450) and Matt (AMR_MForbes) are great people to deal with and very receptive to all the questions I had and still have as I continue to learn more and more about my car and performance. Chris has been in contact with me for over 2 years now and had reached out initially when my car was still leased instead of financed and taught me a lot of great things about the C43 platform. He was constantly reaching out to me and educating me about small things here and there. Being on the East Coast and Chris being on the West Coast, I am sure he doesn't ever sleep because I would ask him questions insanely late at night or extremely early in the morning and he somehow was always responding within the hour. I've put about 250 miles now on my RV3.1 with Special Features Mercedes AMG C43 and the car is absolutely transformed. Simply put, it's a rocket. Everything from the sounds it makes, to the throttle response to how the car shifts now is optimal. I drove to CT where AMR is stationed and Matt guided me every step of the way. He was very receptive to the questions I had regarding performances and finances. He was extremely patient with me and overall just a super personable guy. All in all they had my car tuned and ready to hit the road in about 2.5 hours which is insane. Major shout out to the entire AMR team, they are the best guys I could have asked to tune my car. I can't wait to put the hurt on some owners cars when the pull up at red lights, hahah! One happy customer here!

I went with AMR on my 2019 C43 sedan did the RV3.1 tune, couldn’t be more happier with it. Chris (ig: c_chan450) who’s the ambassador for AMR in California helped me from start to finish. We first linked up on the MB world forum and from there he explained unleashing the beast mode and how amr focuses on not only performance, but reliability and consistency! His customer service is on point, amr is great tuner they developed a wonderful and safe product! The car runs smooth, much quicker, sounds great! I couldn’t be happier! Thank you @c_chan450 Thank you @amrperformance

Have to say these guys have superb customer service and the tune is INSANE on my Mercedes C43. I have only had it on for a few hours and the I can’t stop smiling behind the wheel. I met Chris on IG and he literally responds to any question I have within SECONDS. I highly recommend AMR for all of your performance needs. These guys are the real deal! Thanks again Chris!
