FI is for Fault Indicator light.
You can check the codes to see what it is.
The popping on decel is not uncommon when you remove the backpressure. It is easily stopped by blocking the large hose from the air intake to the Air Injection System. (AIS) A lot of the loudness will go away too.(on decel, anyway)
How did you conclude you were running on one cylinder?
(I have the cobras fitted too.)
EDIT: Is your bike fitted with Oxygen sensors over there?
