Hi All,

First post on here after lurking for some time now smile

I've booked my C200 W205 for a remap in a couple of weeks. Never had a remap or anything fancy like this done before so I'm a little apprehensive.

On one hand I've read most of what you guys have said and it will generally be fine, the car will drive 10x better etc, but on the other hand I am concerned I'll just be reducing the car's longevity by doing so. The car is a 64 plate with 42k miles on the clock. remap from 181BHP to 241BHP.

241BHP is roughly the same as the C300, is this because the C200 is the exact same car but detuned so they can charge more for C300s or will there be differences in the turbo, the intakes, clutch, flywheel ratings etc as well?

Basically I want to apply a bit of science to the "it will be fine" answers. I probably won't be booting this car very often, I just want to unlock the C200 into its true C300 potential if merc have deliberately detuned it. If anyone has had this remap done I'd love to know about it.

Thanks very much in advance for you help.

Depends on how you drive it.
If you drive it hard and use the extra power/torque a lot you will reduce the life of engine, gearbox and drive train.
By how much is pure guess work.

I've just bought a W205 C43, I'm going to map it, just for the extra poke for overtakes and B roads.
Who are you going to?

Its probably pretty safe to be honest. Mercedes leave a lot on the table when it comes to power output in their cars. They seem to hit the performance figures they claim, but not really much more (unlike Porsche!). But it does seem that pretty much every model they do has plenty of room improve. A simple remap is unlikely to push things and there will be plenty of protections built in to stop any big damage.

Not a Mercedes owner so cant commend on the C200 vs C300 differences but a lot of cars have detuned engines. My 981 Cayman S has the same set up as a GTS so can achieve GTS power+ more from a map.

Make sure you get it done at a decent place, Mercedes specialist would be even better. before and after rolling road to see the gains rather than peak power.

Don't go to one of these Facebook man in a van type tuners.
