Be absolutely 100% sure there are no vacuum leaks. At carb, manifold, fittings, tubing, hoses, gaskets and etc. That would cause BIG power loss.
It will seem like carburetor or ignition problems. It's a sneaking symptom.

I repeat, these hot coils and trick ignitions do not do anything for a normal everyday motor. I just sounds cool to say "I have a super blaster, lightning carbonite spark, lightsaber, deathstar coil."....but a guy with a Napa stock coil still blows your doors off.
