Starting with an AFR map that matches the riding style of the individual and takes into consideration the build, both the Zippers system and TwinScan tuned stock ECM, would seem to get the bike to the same optimized level.
But to take either the stock ECM or the Zippers module to a peak performance level, it would still seem to require a dyno in order to tweak the AFR and timing values to produce peak HP/Tq.
I guess I may be missing something, but is the Zippers package anything more than a set of base maps provided with a closed loop system that will tune the motor's AFR to the actual values being called for in the canned base map?

you load the base map to start the bike and give the ecm a starting point. it unes from there to an afr that you select. it also tunes optimum timing and decel fuel.
