GM Duramax 2006 - 2009 LLY, LBZ, LMM

It works so well on the early LLY engines, it was a natural to make it for the newer 06 to 09 engines also.  The power numbers are not as dramatic because GM fixed many of the major problems, but the results are there!

• +9 HP @ 2225 RPM
• +23 lbs. ft. torque @ 2225 RPM
• Cast A356-T6 Aluminum
