So I had this MSD BTM box on my Camaro and I was driving it one morning when it decides to just die on me and wont turn on anymore. So the MSD box is broken and it is still in the car but bypassed so the car drives but we don't floor it cause the timing isn't changed. However I am buying a tuning cable tonight and going to change the timing myself. However, I wanted some knowledge of how much retard I should do? I am running 5 lbs on a Vortech V1 supercharger. If you have any tips those will be greatly appreciated as well. Thanks!
