Chart #1: This is a 4th gear roll-on. Pretty clear gain across the entire RPM range, but definitely more at the bottom and top than in the middle.

Chart #2: The is a "full acceleration" test, where the bike is allowed to come up to idle speed in 4th gear, then dropped down to 2nd gear for a full-throttle run up to the redline. The interesting line is the 4th gear idle with the stock can -- the jagged line is indicative of a lean running engine. You can see that the jaggedness disappears with the race pipe and new tune.

Chart #3: This is a run through all the gears (starting in 2nd, since the tire will slip in 1st). Not a great job of hitting the same shift points, but it looks like there's a good 4-5 HP gain on average.
