I got out sunday for a nice ride, got almost 300 miles and I have to say my sled doesn't have that bog at 7000 rpm any more. I'm glad to see that it actually cured it. Otherwise it runs the same, same amount of mpg. I still will never buy another 600 SDI, but that's a different story. Like I said, good to see they stepped up and fixed them in the same year. Touch wood.
