I bought a Black 2013 C63 Sedan and after 1,000 miles I decided to tune the ECU. I was NOT looking to turn this car into a race machine as I already have a fully prepped, race ready M3 for competition that I used at NASA races. The tune I was looking for was "simply" to remove the restrictions put on the factory and let the motor run free, like it's suppose to be with a more relaxed tuned if you may, but without messing up with reliability.

After talking to a few different folks (they all seem very serious and professional about their work) I decided to go with Cory at Kleemann.

Well, I just want to say that the tune transformed the car. I knew the car would go faster, but I didn't know Kleemann's tune would transform this already fast AMG into a monster. I can still drive it very relaxed (only happens when I take the kids to school) and nobody would know this car had anything done to it.

So I'd like to leave a big thanks for Cory and the team at Kleemann for such a great job. I'm a very satisfied customer and I'd recommend them to anyone looking for a great tune.

My car is in Charlotte right now at GMP getting this same tune (plus LT Headers and an x-pipe) and seeing this thread makes me even more excited.

I can't wait.
