The only engine or exhaust modification I have made to my Brutale 910 is an Arrow midpipe. Will buying and installing the Stage 1 FBF Eprom Chip help performance or EFI on my bike with only that modification? I would appreciate any insight. By the way, my bike runs very rich as I get about 27 mpg and black soot gathers around exhaust outlets. I do not care about mpg, I just think the eprom chip may help smooth out the bike a little and add minor power/torque. For $99 it seems like it might be worth it. Thanks again.
