So im looking to do the software upgrade on my 17 c300 coupe. Ive narrowed down my choices to this AMR upgrade http://shop.amrperformance.com/produ...e-ship-in-ecu/
They claim to give between 55-75hp guaranteed, which for the current price of $479 is pretty damn good.
My question is: has anyone here done this particular ECU upgrade or any other ones for that matter? Did you feel the boost in power? Did you have any issues whatsoever with the car afterwards? Any issues with the dealer regarding warranty?
Any info would be appreciated! Thanks!

Try asking in the C300 sedan forum, there's more posters over there usually.

Hey so I just ecu tuned my c180 (1.6lt). A german company did it. As I've been told, power increased from 156 hp to 198 hp. I am pretty sure I can feel more power but i don't think it became a 200hp car. but I am cool with it. Already made more than 500 km and had no issues so far.

I will dyno test it and share the real results with u soon.
