full system on 2007 S2R1000.
Was getting a rapid bike for it, but rapid bike modules were frying 2007+ ECU's.
Had the full system with stock ECU. Got a lot of "farting" on deceleration with stock ECU.
Added a DP ECU bike feels a lot sharper no farts or pops.
The ducati dealer who installed it said because of the stepper motor, he can't get the idle below 1500rpm
The idle is annoying, it can idle up to 1900 (randomly)
Don't know if the small to large header has any affect.
I'm going to get boom tubes or modify the udder, Zards are going (only going because I want something a bit radical, changing the look)
