Do you mean you used a map downloaded from the dynojet web site? My understanding is these maps are generally a little rich. I'd suspect deliberately to avoid liability issues if bikes started detonating due to lean mixtures.My PC3 was using a ready map from Akrapovic for open system (im using Baffles + Leo Y pipe).
Only way to have it right for your bike is a custom dyno tune from a reputable tuner IMO. If I had mine over again I'd get it flashed I think.
