i Have an 02 Duramax edge with attitude , Have used a Bullydog speedometer tool to adjust stock speedo for 315 tires . also did a Bullydog shift kit,springs in the valve body, My 3 to 4 shift is jerky.Is it the edge doing that? Can I run the edge with efi live and defuel ecm to get it to shift right? I havent ordered efi live yet
