Looking at your chart the dip at low rpms is your pipe but the peak then big dip at around 2300 all the way to 3200 to 3300 would concern me a little like the tuner didn't really tune the bike below 3500 rpms. Tuners will all start of with a canned map they have stored from similar builds and go from there and tune where they really think they need to start. A tuner should tune the entire operating range. With that 259 cam you should easily pull more TQ at 3000 let alone almost 3500 than you did at 2300. Your tune doesn't catch up to the small peak at 2300 till almost 3500 and that is not the pipe or the cam that is the tune.

I'd go back to the dealer who tuned it and ask for one if they tuned it throughout the operating range 2k to 5k or so and if they did why the big dip in tq from 2300 to almost 3500 your tq curve should start and gradually go up to your peak which with the 259E if thats the cam your running should be in the 4k to 4.5k range which I'm only guessing here and then gradually go down after it peaked and where your tq and hp curve meet the hp kinda takes over but to have more tq at 2300 than you do at 3k isn't right. Was the tuning part of the pkg which I'm guessing you bought the parts from this dealer? For instance look at the HD graphs in the stage 4 part number in the SE catalog and see how the tq curve goes up peaks and goes down gradually not a spike at 2300 and then your tq doesn't recover until almost 3500. At 3500 and up from there it should be about ready tp pull your arms off. I'm not trying to be a ahole I'm just trying to help you out and make you realize the full potential of the build and who cares what the final numbers are if you are losing power where you ride the most 2500 to 4500 range. If you can find a another tuner in your area take your sheet with your and have a talk with them. That final number doesn't mean squat if your cruising at 2500 and you whack the throttle and not much happens till you get up to 4k. A bike with less HP/TQ but a better curve/tune than you will pull away from you and you'll be upset wondering why. Hope this helps and again just trying to help you out bro
