I have a 2002 Hayabusa. The first generation Hayabusas' are the fastest. That explains why your 03 is so fast. My ECU was flashed so it will definitely outrun time lol.
@truckdriver_8469 thanks. My other 2003 is in stock form and the first time I took out this copper 2003 I was shocked at the acceleration. It definitely surprised me.
