OM642 DE30 LA red. versus OM642 LS DE30 LA
Hi. I have la big big grand question which don't let me sleep all week- OM642 DE30 LA red. vs OM642 LS DE30 LA which parts are different that gives so much bigger performance (ECU programming would be next step).
I drive a w211 280cdi (140kW), when my father owns w212 350cdi (195kW).
Since my car is not new, I am planning to leave it for chip tuning, maybe cat. delete (I am not sure about that, because I love that there is no smokes behind me, so I can hold that extra HP until cat. will be totally jammed. Also, leave EGR valve working, cause I think this would help for cat., am I right?).
But before that, I am thinking about some `homework`, to find parts which gives better performance. I found good web- EPC, but it's paid 75$. Not so much for year, but I have just one question... Maybe someone can help me???
OM642 on w212 have cat. and EGR valve working, but still have enough power for diesel- 190kW, so that also keeps my mind to not touch that and leave it as is now.
And how much power stock 7-g automatic gearbox can hold?
Any helpful answer will get 58 karma points, I'm not sure about price on black market now, maybe 100 can be exchanged to one `like`.
P.S.- on w212 there is air flow canal for oil cooler, is it useful?

By "better performance" do you mean quicker acceleration?
If so, would it not be easier to sell it and just buy used E-Class with the most powerful gasoline engine you can find?

Judging from the engine, he is in Europe where diesel is way cheaper than gasoline.
Chipping MB in USA is not popular as the option above is easy available, so I think going with the question on European forum would bring better response.
I don't think 7G is going to be a problem here, but knowing the country is essential to give proper and legal answer.

Turn off the EGR, it is always better for the engine and the CAT (actually a DPF).
With the EGR off your fuel will burn hotter and more completely, thereby producing less soot/particulate. This will reduce the amount a contaminants in your oil and reduce the number of regens your DPF has to do, as well as slightly improve your fuel economy.
