    WA 01-05 PPE Duramax standard tuner works on 06 H1 Alpha $400 OBO

    Like the title says PPE standard tuner for sale. $400 obo. I bought it in 05. I don't know if it will work on the newer trucks 06-10 without a reflash. You may want to call PPE if you want it for a newer truck. They are advertised on the sites for an 01-10. They don't make this one anymore...
