Got the stage 1 ECU tune for my 2017 c300 and it feels so much better than stock, better low end and high end power and the pedal feels much more responsive. They also removed the 130mph speed limiter for me, big thanks to Robert for helping me out with that they just updated the file and I reflashed and was done in under 3 minutes. Their customer service is also incredible, they truly care about their customers.

Tune was very easy to install, takes roughly 10-15 mins. If you run into issues just join an online amr chat and they respond within a minute to help you with any issues. Chris Chan made it super easy to purchase and helped me to select what was right for me. The burbles are not very loud, only hear them on downshifts, not when revving but it’s perfect for me. I would love if amr could find a way to override the auto start/stop from turning on 😉 Overall I’m satisfied with my purchase and it has opened my car up a lot since getting it done.

Amazing power. Amazing sound. AMR guys are great. Make sure you have a good laptop with all updated software. I tried on an older laptop and almost messed everything up. AMR was there to help on a Sunday too. More than happy with the sound and performance! Recommend

Had the Comport Pro tuning for my c300 and was running the base stage 2 tune. I worked with Chris Chan to get a better tune and he got me a new file and was loaded into my car by the next day. Service was great and car feels faster and sounds amazing.

Yazen Kinjo –
Just got stage 2 comport suit tune with burbles for my Mercedes c300 and it is amazing, can definitely feel the power in higher speeds on the highway which is extremely important, and the pops are extremely loud. Chris “c_chan450” on instagram was the one who helped me with the process, he’s a great person to deal with and is extremely mature. I wanted my pops louder and In about half a day they were able to get that done and send me my new tune. Amazing company. Also when I was having trouble tuning and figuring out the software I was able to contact AMR on instagram and they would always reply extremely fast and are Able to handle any problems with the software. Most important thing is be patient and just let them do their job.

Chris Chan made my experience with AMR amazing. He walked me through every step and even went out of the way to make sure I knew the product I was getting and what I would get out of it. So far I am stage 1 on my C300 and I’m just about ready for stage 2 plus the DP from you guys. Never hesitate to do business with AMR best in the game
Philip Santos –
Very happy with the tune I received from AMR. Chris helped me pick out what I needed promptly and took the time to have a long phone call with me. He made himself available before, throughout, and after an absolute disaster with usps. The car drives great, and I can certainly feel the performance gains. I’m very happy with the burble file as well. Overall a great experience, I would recommend AMR to anyone that is not looking to cheap out, and anyone that wants a good quality & high performance tune.
Harry Wheeler –
Wasn’t sure which company or brand to tune my car with. AMR Performance is class when it comes to a w205 c300. All the way in northern california I wasn’t sure how AMR would tune my car. Then i met Chris. Chris is Amr’s norcal rep and is an amazing person. I drove about an hour to his house for a tuning session from amr and I couldn’t be happier. He is so knowledgeable and the perfect person to have tuning your car. I am so happy with the results i encourage anyone with doubts about a tune to hit up Chris @c_chan450 on instagram and I promise you won’t regret it.
Drew Zichichi –
I love my comport tuner it works amazing and the process was relatively easy. Throughout the process Chris was an absolute amazing rep and he made my experience a 5 star. If it weren’t for him I would not be leaving the most amazing review but I was very satisfied with the end result and the service from chris!!! Thanks Chris!

Purchased the AMR comport as well as an armytrix downpipe from them. Great service and communication and the tune is insane.
roberto maynez –
I’m very impressed with AMR. hands down they are one of the best tuners , i really loved their customer service. Thanks to @C_CHAN450 i received an amazing customer serving guiding me through the purchase of the comport to the installation of the tune. I couldn’t be happier with the tune, im currently stage 1 with stock exhaust and still has pops. The tune made my C300 w205 race against Camaro’s and Infinity’s modified. I never thought a 4cylinder could have so much potential. I’d say to go with AMR over any other tuner. My performance went up meanwhile my gas economy went up as well, couldn’t have been any happier. Contact @C_CHAN450 for your tuning needs.

First things first, although the c300 isn’t an AMG by a long shot, I bought it for the fuel efficiency and the practicality in everyday driving compared to the larger brother the 450//43. I modded the car to personally enjoy the vehicle more instead of expecting a race car like performance so i did some reviews on the best tunes for the platform (W205) and AMR was the first choice. Although the price for the Comport may seem steep at first, the ability to change files whenever you want is a real attraction and I will gladly pay for a reliable, friendly tune instead of “others”. I was pleasantly surprised on how much of a difference the tune changed my daily driver from something that was okay to something that I look forward to driving on a daily basis. The pops and bang is also a great bonus and it never ceases to put a smile on my face. I want to personally thank Chris Chan, and everyone in the HQ for their amazing customer service: Chris responds instantly and stayed up through the night helping me resolve an issue and I am sold on the professionalism of his help. He even texted me to make sure that everything is going smoothly and I know that if I ever have any questions, he’s there to help and it’s rare to see such great customer service that AMR provides. That being said, fast shipping, amazing customer service, and reliable tunes are what is gonna bring me back to AMR if I upgrade in the near future to an AMG.

When I realized that my car had the potential to be faster, I told myself that i needed to start adding things to make the car more enjoyable, i quickly realized that i was SOL when it comes to buying parts because of how little i know about them or how they will effect my car. Now talking to someone that works for one of these companies was essential, when i decided i wanted to get an ecu tune i started to look online at some of the popular products that kept coming up. These Products were the JB4, Race Chip, Etc. and when i tried to get into contact with these companies, no one got back to me and it took a good 3-4 days to hear back from them. My good Buddy has the same car as me and was having the same problem, we didn’t know what company to get our tunes from. And one day he calls me on the phone and starts telling me about this company he saw online called AMR Performance, at first i thought it was going to just be another thing that we had no idea about but when we got talking about it he said that he has a salesman’s phone number, going by the name of Chris Chan. Once i hung up the phone i googled the Company and immediately had 1,000 questions, and the second i had my hands on Chris’s phone number he was there texting me back that day, if not 20 minutes after i sent the text. The customer service that Chris provided was extraordinary, he was always willing to help me and my buddy, even taking the time out of his day to facetime with us for literally any question or concern we had. I am very thankful for Chris, he helped me pick Amr, he showed me why they are the best. Once the tune was in my car it was like a light switch to the power, i love it so much and it makes me appreciate my car so much more. I am only on stage 1 and my car has at least 65 additional horsepower, burbles a bit, and i only have a cold air intake. My buddy has a cold air intake, charge pipes, and the downpipe needed for stage 2, his car has at least 125+ horsepower, and sounds like an AK when he wants it to. PICK AMR!

I Just want to say wow! Honestly I am speechless. No words can describe the attention to detail and customer service this company has provided. I was really hesitant about buying a tune at first. but with the help of Mr. Chris Chan I was all in. I was on the fence for months about tuning my car. Chris Helped me through the process. I am amazed by the amount of passion he has for the industry. I called him at all hours of the day to trouble shoot any questions I had. At first I was running just the stage 1 tune. It was as simple as he said plug and play. When my Weistec Downpipe came in. It was a game changer. I was able to run my stage 2 and let me tell you…. GAME CHANGER. The power.. the torque.. the responsiveness of my car… best part was the noise , Burble tune and Flame Tune. I have a 2017 C300 and I can hands down say this is one of the best investments I made to the car. Ive had the tune on for about 3 months now and my car is still running as strong as ever. Daily Driving is such a blast. Everyday I just look forward to taking the car out on the town and turning heads. The biggest concern I had was I did not want a blown engine or turbo. Through countless phone calls, Texts, DMs chris reassured me that there was nothing to worry about. AMR tunes the car in a safe manner that you dont have to worry about wondering about the what if. The handheld comport came with 6 tunes… It really is as simple as plug and play. My car is now like Dr. Jykell and Mr. Hyde. With the downpipe My car is still comfortable to drive in comfort mode. I have full conversations on the phone and with passengers. In Sport plus is where the fun begins. With the added power and torque… This tune makes you want to get into a little trouble. It certainly is a head turner with the burble and flame tune. People ask me all the time what car is that and what have you done to it? I always tell them its just a C300 and Chris Chan from AMR Performance is the man to talk to about your tuning needs. He’ll do you right. So is it worth it ? 100% yes.. it is worth every penny. It’ll change your sluggish c300 into something more fun and for spirited driving. you’ll never want to leave the drivers seat.

I ordered the comport tune for my 2016 c300. And let me tell you the tune is absolutely amazing, I was nervous because of the price, but it is worth every dollar. I run a catless downpipe and the burbles are amazing. The shifts in between gears feel great. And the gears pull so much faster through the rpms. You can feel a huge difference after like 1 or 2 days. So for the tune aspect I would give it a 12/10. But now the customer service. Chris Chan helped me from start to finish. Whenever I needed him, he was was there. FaceTimed me while I installed. And was extremely welcoming to all the questions I had. I rate the customer service 15/10. Absolutely amazing company with excellent products. I will be coming back for any other tuning needs, AMR is the company!

I research about tunes for a while and definitively I make the right decision with AMR. Customer Service here also is fast and effective, Matt and his team is always taking good care of customers…Thanks guys!

I wanted to post my experience with AMR Proformance. I spoke with Matthew on the phone about purchasing a comport Tune for my 2016 C 300. He answered my questions with extreme detail and patience. I also own a 2018 S63 and a w205 C450. He made it clear that the tune will make a night and day difference, while making sure I knew that it would not turn my C300 into a 63 AMG. I was mainly buying the tune because any who owns are has driven a w205 C300 knows there is no 3rd or 4th gear pull. Once it gets to third there is no paddle left. After 3rd it Accelerates like a broken dump truck. I purchased the comport tune, got it shortly there after. I installed stage one in about 10 minutes start to finish. Before I continue I want to explain my c300 is modified with A true closed Cold Air intake ,gfb blow off valve, after market turbo charge pipe, resonator delete, muffler delete, stright pipe from cats back, 20in Lexani superlight rims wrapped in Michelin pilot sport cup 2 tires staggered with 10 and half inch wide out back. I stated all that to be fair and let it be known that my c300 is not a stock car. With that said the first time I pushed the paddle after installing the tune I was blown the f#&k away at the paddle response. Took it out on side streets to test the burble mode. That burble is extremely lound and satisfying. Took it out on the highway and 3rd 4th 5th gears are all now ready to kill. I was at 3 digit speeds with plenty of paddle left. Absolutely blow away my expectations. I do not have a dyno. But I do have a completely stock w205 c450. So I lined my AMR tuned C300 up with the stock 450 with my son behind the wheel. 3 times we raced from dead stop. 1st time he got me by a bumper. Next two times I got him. 300 jumps out hard as hell with the AMR tune. And stays hard in the up shifts. The fact thst the C300 can even leave the line with a C450 let alone beat it in a 300 yard sprint is impressive. Anybody who owns a C300 should be drooling for the AMR Tune. Its wroth the money. I will be shipping my S63 to them to do a in house tune. If they did that too a c300 I can’t wait to see what they do to my heavly modified S63. I will be going to stage 2 on the 300 next week, just waiting for the downpipe. C300 owners don’t sleep on AMR Proformance tune.

Where do I start! AMR has been very accommodating getting my tune dialed in just the way I want it. Even down to working on Saturday and Sunday making sure everything was finalized! They are very knowledgeable when it comes to Mercedes and took the time to filled me in on things I didn’t know. I highly recommend their tunes. The difference in my car has been night and day, I will definitely be using them on my next Mercedes build!
Sanel Korkutovic –
