The COP systems you usually see on DSMs are cheap junk is the problem. You need good coils and a real CDI behind it like an M&W box. And why do COP if it's still going to run wasted spark. Every DSM COP setup I have had here at the shop has had very sketchy wires running to the coils also. Look at Curt Brown's last adventure to th dyno with a COP on the car.
