FS: Duramax Superchip 2855 Flashpaq

Recommended Posts



Just found this hiding in my closet. I used this chip in my prior owned truck which was a 2007.5 (updated body style) Chevy 2500 HD Duramax LTZ diesel pickup that I owned for almost 6 years. It gave me a considerable amount of pickup at mid range and highway speeds as well as boosted my fuel economy a few mpg's. Highly noticeable gains while towing. 

$250 firm & I'll ship it to your doorstep via USPS anywhere in the mainland US for no additional fee. Retail cost for this chip is $325+.
