Granatelli Motorsports Predator Tuner
01-03 Gm/Chevy Truck/SUV Duramax Diesel

This Granatelli Diesel Tuner has 4 performance settings and can read diagnostic trouble codes.
The performance boost and mileage gain was incredible. This tuner is in original box, with manual and is like new.
I am selling it because I no longer have my truck.

Price is $180 plus shipping cost. Email me at [email protected].
