On a realistic dyno these could measure 172-192 bhp well down on 201 , you could see 235 bhp , it will be real with a real gain around 45 bhp , don't get hung up on bold claims from companies with generous dynos or marketing .

If you want more , 350 CDI .
 
What the closest I can get to 350bhp on this
Welcome to MBClub.

DMS claim they can increase power up to 259 BHP (GAD claim 250 BHP) which is probably as much as you can do without spending serious money. If your pockets are deep then I dare say you could go higher, but pit get’s expensive very quickly beyond remap.

Try calling MSL to see what they can do too as they’re a Mercedes specialist.

235 is a lot less than was I was thinking but I didn’t think getting to 350bhp wasn’t realistic, really grateful for the advise thank you

That great I’ll give them a call and find out what I can do because didn’t want to spend too much but I was considering turbo upgrade and intake upgrade but wasn’t sure if that was going to get me close or how expensive it could get, thank you
 
GAD used to claim alot of things..

But then they had their own 'realistic' dyno installed and they had to drastically change their claims as they then began to publish the dyno graphs .

You now get the truth , albeit the most highest 250 CDI bhp dyno plot is 235 !!
 
Not to say you couldn't get close to 290 , but it'll be a few bucks .

 
See discussion here:


And see also remapping option here:

 
AS per the link in Gazwould's post above, the E-Class Coupe C207 of the this era is in fact a C-Class Coupe C204 with higher-end trim, both are based on the C-Class Saloon W204, so look for engine mods for the C250 CDI (W204 facelift), there are more commonly listed than the C207/C204.
 

Except it won't be 255 as they are an example of a generous dyno coupled with lies caught out by me !
