My E320 Diesel in still great at 206K, I tuned it at 55K and a few more times as dealer kept re-flashing it.

This "new" car is the curb weight of a Sprinter with a similar engine, and the other chip is for a Sprinter.

I don't always cruise empty highways in Utah, Wyoming, and Montana, but when I do I want it to be in a tuned diesel.
