You're likely not going to be far off the DP ECU trace provided your bike has had a proper tune and is in good condition. Each bike is a little different and you cannot really get reliable published numbers using a given combo of pipes and ECU.
Great question, great response and great report by Brad.
Based on personal experience with my bike and jduke's in Georgia, i would not believe that a DP map is necessarily the best for your bike.
As SS904 stated "every bike is a little different" Even what you perceive as a minor mod, may actually have quite an impact, which could be positive or negative in various ranges/regions of riding.
