anyone use a D.U.I. tri power ignition?

i'm replacing it cause i had prolems with it skipping before my engine rebuild. new cap, rotor and wires and it was still skipping pretty bad. Figured that i would change the ignition system while rebuilding everything else. I went to D.U.I cause i wanted to clean the engine compartment/wiring up a bit. Originally got thier system that is like a cheby HEI, but it didnt fit so i returned it for the tri power system

thanks,

Steve
