Semi-unrelated, but I'm seeing more dyno reports which suggest that the db killer in the MIVV decat pipe robs the motor of horsepower (restricts exhaust). Check out Ducati.MS for some great ECU/fueling related threads. Personally? The FatDucs do a great job helping the closed loop fueling down low on a stock exhaust bike.
