You all might not believe me, but I have been driving a lot of high mile duramax trucks. Many have had 300,000 plus miles, and have ran as good as ones with 100,000 miles. I drive high mile gas engines and they still run great after having over 250,000 miles on the clock. The 06 crew cab is a little riddin hard , but its performance and ride is still a 9 out of 10 with 300,000 on her. Black smoke at heavy throttle is all I experience, and I figured its been overfueled. I will try and find out if its been programmed.
