in case you are referring to me: Sorry, I don't have any further details then specified here. Hope that helps!
...and Joe, if you're reading....I would appreciate your specs for the engine tune you did to your truck, valve lifter clearances, injector nozzles and injection pressure.
Re. valve lifter clearances: He set them a little bit "closer" but for warranty issues I don't want to publish them and recommend to set to the technical specs from Mercedes Benz!
with kind regards from Bad Kreuznach, Germany.
