Absolutely. Tried over 20 times.

There is no part number only a sticker that says "duramax"

bios 6.01
2002 Siverado 3500

just bought truck, predator was already installed, seller told me he had the truck setup to the 65hp tune.

I need to change the tune to tow mode since I need to go pickup a 12,000 trailer.
