Duramax 6.6L '04.5-'06 (LLY)

8th Digit of VIN:  2


Great choice on the LLY, it was one of the first trucks to have a variable vane turbos.  These spool quick and have plenty of boost at the top end as well.  Tons of options for these trucks and some cool things you can do with custom tuning, like a turbo brake.  Enjoy your Duramax LLY and let us help you spruce it up a bit.
