I have a 2000 FXSTD Carb Deuce. I recently upgraded to the street legal SE ignition module and SE 8mm plug wires as well as the SE plugs. The engine is stock with Stage 1 A/C upgrade and V/H pipes with no baffles. Would it be worth throwing in a SE or other performance coil? I realize there will be no hp/tq increase, but will it help ensure clean burn? The highest grade fuel I can find in Kansas City Metro is 91octane if that makes a difference.

Main goal for the bike is just make incremental improvements when I can afford it. All comments/opinions welcome.
