I just bought a 99 e300. Dieselmeken timed a 99 e300 to 10° atdc and installed a modified injection pump. Is it possible to get a performance improvement by going from factory timing of 15° atdc to 12° atdc.
I did the exact modification on my 85 300sd and it made a noticeable improvement. But I haven't seen anything, other than a video from Dieselmeken, that deviates from the factory setting.
