Hello Everyone, I'm brand new to the forums and have a quick question for any with some knowledge on the topic.

I have an '04 FXDL with Reinharts and a heavy breather that's otherwise stock except for a new map when upgraded the pipes and breather. I found a Screamin Eagle ignition module online for my bike at an unbelievable price. However, I'm wondering if I'm wasting my time installing it if I have no other performance upgrades like Stage II, cams, etc.? I would appreciate anyone letting me know what they think. - Thanks!
