Interesting... the chart shows about 16hp gain at 2500rpm.... but still a darn good boost for $300 on a Mercedes. Hope you I'll give follow on update on real world performance over time. thxI have a 2013 SLK 250 (gas) I added a Dinan chip (25hp and 35lbs). Oh my gosh! The best $300 I have ever spent. Thought I should pass on...
The experts will jump in when they sober/wake up to refute my commentI’ve never had a custom tune or race chip before. Is it possible to remove these without them leaving a “fingerprint”, or is this something better to get once the car is out of warranty?

Since it is usually your ecu that is 'reprogrammed' for these 'upgrades', unless one has an 'extra' ecu to swap out say when you go in for service, it is better left until out of warranty in my opinion.
It is not like a SmartTop where you have a 'disable setting for service shop visit' mode
So RaceChip as a German Company do not know what they are doing and selling us?Folks,
please don't mangle your cars with these kinds of modifications.
An external "chip" box works by falsificating sensor data to the motor ecu, and in the long run will end up in situation where sensor falsification will lead to unwanted results.
If ecu modifications are needed, please have a remap on the ecu. By this way, sensor data is remained as should, and things cannot run into conflict situation.
Oh, I don't doubt at all that Racechip wouldn't know what they sell.
What comes to detuned engines.. One can do a part-by-part comparison of a detuned and "mother" car, and finding no part differences there, it's just a matter of uploading ecu maps from the more powerful one.
Or, in case of some M013 versions, just a matter of getting rid of reduction tables. Just like a 280cdi vs 320cdi on OM642s.
Although i got my RaceChip Pro 2 for just £50 off Fleebay they do cost alot more new close to the price of an ECU tune for the top version,i like mine because it can be removed as and when needed as i stated in a post above and also i'll install it in a few seconds before a nice sporty drive,all winter and even to this day it's capped off on it's wiring harness with a simple blank plugin that restores it to stock instantly,no point installing it in winter here in the UK for day to day commuting and it's adjustable by removing 4 screws inside the chip,Racechip support were also excellent online,advising me of settings and answered my every question within a few days.Coming from experience with mangling perfectly good cars for more power; if you want a more power, either pay for it (kleeman, dinan) or start learning.

I had an old 5 cyl. Audi that I put a powerbox on. it was probably $15 and I was young. but I'll be darned if that car didn't have 15 more HP... unfortunately, the car recognized something was up and it would throw a coolant temp light at me... A competent tune would have solved issues like that.
