Slant 6 turbo how to set timing please help I will even pay

I am not to familiar with slant 6 timing but i have been researching turbo set ups for a while and currently building a large turbo motor for my cuda. what most guys seem to be doing is locking their timing at max timing that the car runs. My cuda is 38* total. Then they retard the timing 1-2* per pound of boost with a retarder like the MSD units. The BTM will only retard 15* total but that should be plenty unless you decide to go with more boost. If you want to get fancy there are a couple MSD units that you can program with a laptop or additional handheld. Those will allow you to set up a retard map in a time frame and timing for each cylinder. hope this helps
