Yes the map is adjustable. With TuneECU it's only $20 for the cable, Tuneboy is more expensive, but can get you an extra 2000 rpms. A tuner who knows how to use either can get you more power without a Power Commander, or similar device.
Hotter cams don't necessarily make the low end unfriendly. With my 265 hp package the bike is still very calm below 4500 rpms, and will walk away from sport bikes when you get into the power band. She's the best of both worlds now. I love my bipolar b!tch!
