What MSD unit can I buy to adjust my timing with the retard pills, I have the 6al....If im going to be doing alot of timing changes this seems the only way to go


I use the 6al, with the msd 3 step box plugged into the rpm chip slot, one goes to the retard box and the other is the launch chip.

If you got the msd site and look at all the different configs to istall its pretty easy to figure out what your doing and what you need.
