Just installed Race Chip Ultimate piggyback and the throttle controller on my 2015 W205 C250. Installation took about 1 hour for the piggyback and 5 minutes for the throttle control. Race chip Ultimate most gain is between 2000rpm to 4500rpm. The sweet spot is 4000rpm. Their claim was 30hp increase and 60nm of torque increase. Awesome! I will dyno the car sometimes next week. The response throttle really helped with the acceleration. It really helped to get the turbo boost much faster. I can feel the response from as low as 1500rpm.

Done this on my W212 E200 and I love the response. Did you manage to find out what software are they running?

I believe it's TB44. F/1 setting. It is the latest software update from Race Chip.

I'm running on TB44 as well. Running on 4/1. I believe you should be able to push it a lot more with 4/1

I did push it one click further, unfortunately, the gas quality around here sucks. So, there was a little bit of knocking. They told me not to push it if the gas quality is bad. So, back to default setting again and no more knocking.

After installing racechip , did you ever went back authorised dealer? Does this thing void your warranty. Just curious since your car is still under warranty. Really interested to find out more
