I have a 2012 hayabusa has bcm filter dekelvic 9" cans and ecu flash by ivans preformance. The problem is that when I rev the engine the rpm falls as normal till 2000 rpm than slows way down to idle. start up cold is fine and the problem dose not happen while cold. I checked for vacuum leaks none found idle i stable warm no hunting performance is perfect no hesitation or flat spots and no popping on deceleration
I'm thinking maby a sync is needed or tis something in the program what say you?
