Hi Folks. I've been studying this topic for a bit, and thought I'd share my research.
Yes, the AI can be removed in much the same manner as the carb models.
Just don't remove any hoses from the throttle bodies!TuneECU can be used to disable the MIL engine light if the AI electic solenoid is removed. So far so good.
The doubtful point is dependent on what market your bike has been made for. EFI bikes have oxygen sensors in each header pipe. They can be disabled in TuneECU as well. It is recommended to remove the O2 sensors and install a plug if you are going to disable them. O2 sensor plugs: M12x1.25 pitch.
The gotcha is for those of us that have catalytic converters in the header pipes. From my reading, the North American headers and exhaust pipes have the catalyzers.
If the AI is removed, it will be putting out a richer air/fuel ratio which will eventually plug up the catalyzers.
It is fair easy to tell if the exhaust pipes have the cats in them. Look for this weld seam:
I just put on long TORS on my 2010, and it has the cats in them as well, and is a 'see through pipe'.
So, in conclusion, it might be more of a problem to remove the AI from EFI models. My personal take is to sit this one out and see. I should state that not too many people with EFI bikes seemed to be concerned over this, just me

Please note that with the advent of TuneECU, the use of a resistor to fool the ECU is NOT REQUIRED. The thread above has been updated to reflect that.
I should also add that I'm no expert here. I'm just trying to relay this information to this group. If I've missed something, please share.
