i'm pretty sure this slip on doesn't have a cat? if it doesn't, i doubt it would cause a problem like this but who knows, maybe the ecu tried to adapt over the 100 miles and is causing issues now. good luck with the resolution. i have a fairly new 2019 1200s with 1,300 mi and being my first ducati, i'm crossing my fingers with the whole reliability thing too.No map. ECU is stock. This model of the slip on doesn't require a remap. And I've been running with it for 100 miles so I guess an incompatibility would have surfaced before now.
