Been loving the Hyper SP and getting out on it every chance possible. When we first installed the Ternignoni full race system, we decided to pull the air box and add cone filters. Even with the Termi upmap, the new intake solution had created a flat spot in the power delivery around 6k rpm. Rather than going for a custom tune, we opted to just reinstall the airbox and let the Ducati breathe as it was intended. MUCH better.
After talking with some local Ducati master techs, they explained that the 4-valve Ducs don't need to breathe the same way a 2-valve would. If we were going to race this bike and were trying to squeeze out every last little bit of power, the custom map would be the way to go. Considering the Bullitt SP is a work horse, a commuter, and a weekend ripper, we wanted it reliable, and opted for the stock airbox.
The bike feels much happier and we're truly enjoying the new exhaust. This bike is fun in just about any condition!
