I have the MSD 6530. It's a nice little ignition controller. You can set 3 different RPM limits - one for burnout, launch and top end. You can set the timing curve by RPM. A MAP sensor will plug right in and you can also use that to control timing by boost. You can have it pull timing at launch or for nitrous.. If you haven't looked through the instructions yet, here they are:
