250 vs 300
Like with BMW, F30 320i and 328i has the same engine but some engine internal part is different (328i has thicker cylinder for higher turbo compression).
Racechip only has it for GLC 300 so wondering if it works the same.
That's what I am doing here.

You notice that for 220d (163hp /170hp) and 250d (204hp / 211hp) each of them have 2 different power output.
As far as I know , 250d only comes with only 204hp, while the 250 petrol is rated at 211hp.
So the racechip for 250d(211hp) should be the one for the 250 petrol instead.
Just drop the manufacturer an email to clarify.
I am still under 3 years warranty for my 250 petrol, will only be getting the racechip after my warranty period.

Do you know there's any internal difference between 250 snd 300 (e.g. cylinder being thicker, turbo boost is higher, etc.)?
