You can't.

Why?

If it's already tuned with a K&N and D&D, I would not bother doing anything else. I was just wondering if a race ECU would squeeze a few more horses out of it. Front end gets pretty light under hard acceleration. I am not going to blaspheme and say that it has enough power, but I'm not sure it's worth the $$ for the small gain (if any) I would be getting if it's already tuned. Either way, not a big deal. I'm probably just going to enjoy riding it like it is. Thanks for letting me know I can't tell if it was tuned that way.

I would hazard a guess that the K&N and D&D existing on it would leave me to believe its been 'tuned', and if it runs well, I wouldn't mess with anything. IMHO.

If you are computer literate and familiar with tuning fuel injection yourself, visit Rev-Mo.com and play with the tune yourself. I recommend searching any Buell forum for 'Help! my buell doesn't run well anymore' for research.

If you are not, and want the confidence and security of a tune you know, visit IDSpd.com for a plug-n-play option with zero drama.

Thank you sir, for sharing the options. I will keep it as is and be grateful I own something with 2 wheels. Keep the rubber side down.
