As your bike sits now, the EFI will keep the air/fuel ratio at or around the factory setting of 14.7:1 in the closed loop mode only. This is still really lean for the engine and was only ever to keep EPA happy. In the OPEN LOOP MODE(which your bike goes into upon special factors and conditions, like rapid acceleration, etc.) the AFR will be much, much too lean, leading to the ultimate destruction of your engine.
If you purchase a re-cal from your dealer(stage I download), they can only return the AFR back to EPA standards, even in open loop mode. Pro Super Tuner, TTS, Power commander V, etc. including canned mapping thats nearly perfect or mapping done by a tuner that knows what he is doing are some of the options that can put your fueling where the engine will run right and run cooler, whether installed by a dealer or you.
The performance by way of torque and HP that you should gain by getting the fueling right will probably be fairly substantial.
