MERCEDES-BENZ TCU TUNING

AMR Review

I’ve had the pleasure of working with Chris Chan on upgrading the performance of my 2014 E63S. Given the complexity of the programming involved with tuning a car, I was quite skeptical that it would improve the overall performance of my car.

I was completely wrong. AMR’s performance tuning suits are world class in the realm of tuning applications. They are head and shoulders above the rest.

I was fortunate enough to have purchased the stage 2, and TCU tuning applications, and it was the best bang for my buck that I have ever invested in increasing the level of performance in a car!

The engineers really did a great job of creating an MAP application that integrates and works seemingly with the car’s technology! Not only was the installation was painless and fast, the overall drivability has improved significantly! It’s like this is how it should have come from the factory!

Also not to mention the outstanding customer service! Chris Chan was readily available to answer any questions thoughts or concerns that I had! He was there step by step with engineers standing by to assist if needed! If fact with my current job hours I had to do my installs outside of normal working hours and on a weekend. Chris did not hesitate to assist and made his team aware just in case we needed additional support.

If your on the fence about tuning your car, or have had bad experiences in the past, give AMR’s line of tuning applications a shot! I promise you it will be one of the best decisions you’ll ever make!

I worked with Chris Chan to learn about all the upgrades I could do to my 2020 E450 Coupe. I started with the ECU and then did the CPC and then the TCU. Once I started and experienced the difference, I wanted all of it. It’s like driving a different car. Chris and the engineers were extremely knowledgable and were very patient with me. They were there every step of the way. I would highly recommend AMR performance and their products.

Great upgrade when added to my comport pro tuning suite stage 1 tune. Super quick shifts, no delay and I even feel the car pulling harder. Its like a tune plus a tune haha ... Thanks AMR, you guys rock!

The TCU is awesome. Really improved the overall driving experience of my M278 E550 4Matic even when I flash my car back to stock.

But what is even better - AMR customer service. They worked with me to improve the TCU calibration and to work some issue so was having with the software due to my laptop.

Recommend them 198%!

Amr have the best community service and performance that I have seen from any other tuner. To start, their sales rep Chris helped inform me about everything they do and what sets them apart from other tuners. Before I had AMR I was tuned by DME which is known to be the fastest. I was constantly loosing races to people I should have beaten, the power would die off over 100, my car was running poorly and I felt that my car had way more potential. When I flashed my AMR tune everything was way better. I was gapping people that would normally gap me and after every shift you could feel the car just keep pulling like a mad bull on crack. Secondly on the community service side they have been nothing but helpful. My ecu was missing codes from my DME tune and AMR focused all of their time on re writing my ecu so I would be able to flash their tune. Lastly most tuners copy the same file onto every ecu which means that you will have to ship your ecu in with the risk of loosing it. I have learned that AMR has engineers that write your own tune tailored to your own car so I was able to flash it at my house. They are really the best out there.
