C300 4Matic W205
Short C300 OE Tuning review
I've got a 2015 C300 4matic and bought the OE tuning tune last week that claims ~55hp

Getting it was easy, one thing to not is you do have to get your cars ID on the ECU tuner and send it to them to get your actual tune. I sent them an email mid-day on a Friday and they got it back to me within an hour, just don't try to set it up at night for the first time or you'll be disappointed.
Setup was easy as long as your read the ECU tuner prompts correctly, you will have to turn the dashboard on and off quite a few times and I got ahead of it at first and got an error code. When done properly it takes like 3-5 mins to apply a tune.
Performance is pretty good, I've used one of the bolt on turbo thing from Dinan before and this is definitely a big step up over that. The car is still definitely not a rocket ship, but you can get pushed back in your seat much more consistently than before. I don't have a great place to do 0-60 runs so I've only taken one shot at it so far with bad results. I used a drag racing app on my phone and it gave me a time of 7 seconds so I need to get out and try more runs. I'd like to test with lots of variables like traction on/off, manual vs Sport+, building boost vs not and stuff but it will take time. In real world driving it's very impressive, I've driven a CLA35 and it feels similar to that. As long as your rpms aren't super low you can pull hard out of any corner and generally get pushed back in your seat when you push it. I do some autocross with my car, can't wait to see how it does with the extra power in the corners.
I was looking at buying a new CLA35 but my 2015 C300 with this tune it's close enough that I won't be upgrading. I'm running all seasons right now but once I put some summer tires on and drop it an inch I'm hoping to have some good times at the local AutoX.
