Silicone inlet coupler

Seems a little short and not many layers of silicone

The best!

Besides being the only option for obd flashing, the tune I have to admit is amazing. Car is an absolute animal. I am lucky to have found AMR Performance. Too many people in these groups shipping their ECU out to tuners and having problems, I was glad to find such a product. You guys engineer the best, keep up the good work!


AMR came through with flying colors! I have been searching everywhere for an OBD solution. No company makes it except AMR! So I ordered it. After a couple of days, it arrived on my doorstep and I removed my jb4 piggyback and installed the flash using my laptop. Super easy, took less than 5 minutes! The car is amazing! Pulls hard and a lot smoother than the piggyback! Thank you guys for listening to the community and coming through for us! AMR FTW!


Completely transformed my Turbo S! I can not even explain in words how different it feels! Amazing throttle response, boost hits hard and pulls forever! Thank you guys for an awesome product!

So easy! Worth it!

First would like to thank the staff at AMR. Simply amazing! Customer service is top notch and when it came to the product, I could not ask for more! Install was straight forward and easy! Car is night and day! Amazing experience! Thank you guys!

AMR Performance Review

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!

White Glove Experience

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.

Best tune ever!

I have been searching for a tune for my Vantage for a while now. Everyone wants to ship in and they all offer tunes with no experience with the car. Came across someone at a local car show with the same car who went with AMR Performance. So I decided to contact them. BEST DECISION EVER! Not only where they extremely knowledgeable but they are software engineers and the ONLY company that offers an in-depth tune with OBD flash and support for this vehicle! Took me less than 2 mins to connect and flash, worth every penny! You guys have a customer for life!

Great Customer Service, always got a reply within a few minutes even out of normal business hours to answer questions etc, great tune, great power


Great service

I looked around for a while for someone who could get some extra power of my mercedes until I found Amr. I noticed they already had plenty of good reviews and happy customers. Amr and Matt specifically were very helpful and answered all of my questions. Customer support was top notch and all of their instructions were very clear. Excellent response time and care. I will continue to use Amr for my future upgrades on my car and any other vehicles I work on


Although you will see the gains, the downside is that the 4matic 9g tronic will not handle that much torque without modification. Luckily those are inexpensive.

AMG C63s AMR Stage 1 tune installed

Just had my Mercedes AMG C63s tuned by AMR. My initial impressions. The car is absolutely transformed! Incredible performance gains for the price. Turbo lag is gone! Shifts are crisper and smoother. Car is now an absolute beast. If you have an AMG get this tune and unleash the true potential of your car.

Amazing product and unbelievable customer service

AMR is the ONLY play with tuning and Chris Chan is one of a kind. He seems to be available 24/7 with any questions or concerns. I cannot recommend this company, product and service enough. Truly an incredible team. #AMR

Great service!

Thanks for the great parts and service!

Best Tune Ever

This was the smoothest most worth it process I have ever been through Chris Chan sold me on the product and not only after selling it to me , he was there through every step of the installation I will recommend this tune to anyone thank you AMR

Stage 1 DONE !

Took a few months but I hung it because the car is faster after your tune

Sounded good from the first start

I bought the tune for my AMG E43. Because of my schedule at work it took me a while to flash it. Ran into a couple of problems, none of which was AMR's fault. Finally flashed it this morning when I got home from work at 0700. When I started it after the flash, even in the default comfort mode it starts in, it sounded more aggressive. I can't wait for an unobstructed freeway on ramp! But 100% great customer service and attention to the customer. If you want a tune for a car that they cover, go for it! Thanks to Chris Chan for answering my questions and helping me out through the process. At some point, I am getting downpipes and will go Stage 2.

Love it

Makes your c300 feel like it should of from the factory! The people at AMR are there to help you when you need it and very professional. If you own a c300 get one of these you won’t regret it.

Comport tune

Top notch product and customer service!! Will definitely be doing business with AMR moving forward!

Love it!

Bought this a couple of weeks ago for my Porsche Carrera 4S. Love it! Flashed the tune and took it for a drive! Scared the wife lol .. Had her pinned in the seat the entire time. Keep it up AMR!

definitely worth every penny

the best money spent everyone else wanted me to ship in my ecu but due to my kids, I can not have the vehicle down. Came across AMR and Robert on instagram, decided to pull the trigger. Talk about an easy install! I am not much of a computer guy but software was straightforward forward and flashing was quick!!!!! Really woke this car up! Makes me feel like I bought a Turbo S lol ... thanks guys and keep it up!
