well, I had the pc installed and custom map made. Before the map was made. The made 152 hp. after the map installed. it is 154. only 2 hp gain. I ask about this and the tuner told me that it not all about hp, but also drive ablty. I told myself that i spent $500.00 for a lousey 2 hp. The drive home was something else. the bike is more responsive. it feel good when i crack the throttle. I was impress with this. Now can somebody explain to me why this happen with only a 2 hp gain.
