I've based my comment on the configurator - try to add the DTC software without the full exhaust - it won't let you. Do you mean you had the DTC software for slicks added to a stock bike? My understanding was that you needed the Akrapovic map installed for the dealer software to offer the DTC for slicks software as an option.
Excellent. Definitely gives the rear more grip and any adjustments it makes are smooth and predictable. The bike is pretty good as it is, this just gives it more of an edge. The Ducati spiel is that is makes more predictive changes to get ahead of it getting out of hand. It definitely feels like that is what is happening.
