I already have the MSD ignition model number PN6211 and was wondering which retard unit should i go with!!
My MSD already does do retarding but on RPM i need a retard unit used on BOOST
ANY HELP WOULD BE APPRECIATED Thanks

 

If you still have the old forums at FXtreme bookmarked, I seem to remember Onpol posting his exact MSD part numbers for the DIS-2, Boost retard module, and tach adapter.
