Baseline testing with the MSD ignition showed the Hemi was increasing power output on each pull. We installed the taller and wider D.U.I. distributor with only the 16-volt dyno wire to run the Hemi D.U.I. The stand-alone D.U.I backed up the MSD's numbers and power still increased on each pull as the Hemi continued breaking-in. The D.U.I. did well against a team of racing ignition components.
