i'm in the debate of ordering a power commander for my bike. i have a k&n drop in, (stock header i believe? no cat) and a scorpion slip on. i think my bike is running a bit lean, but i need to check my spark plugs to confirm it. anyways, i'm looking to get one, not for power, but correct a/f ratio. my question is, the base maps you can download onto them for your bike, can you run that map just fine, or do people normally get more tuning after that? i'm not really wanting to get my bike tuned, i just want a map for my mods that will work decent enough on the street. any info can help me here. thanks.
