I have an Edge EZ on my '01. 5 and it serves me well along with the other mods I have. I have an elder friend that has an '02 4x4 auto 3. 54's and he wants a little more go. I suggested that he can run an Edge Ez and keep it on the low notch. I bought mine used and it has worked flawlessly for 6 years. I can't find a used Edge. I found a 1 year old Bullydog Torque dog and thought it might be as good or better. It has a switch-on-the-fly, stock, 30hp and 60hp settings. Anyone out there using one? How do you like it ? Thanks for all info.
