I have had this truck for a bit now and am looking for more performance as well as firming up the shift points. I am not shure if the Super chip flash-pack Tuner or the Hyper tech Max energy programmer would be a better choice. Both do what i want supposedly and they cost the same. But does anyone have 1st hand experience with either of these models? Did they work and did they give you hp and tq gains they said they would?
