Have you road it yet? Can you feel the dip? Ride the snot out of it and see what happens.
I found a sheet GMR did in a 113 with that cam and a fatcat. Table top flat. However, I do not know what compression it was running. He did say he was surprised by the cam in that build, not the norm.
Going to come down to what you want. If you like it how it is ride it. Would a 2-1 pipe void the warranty? If not, and you want to get one, do it. It won't hurt your build now or if you change it up later.
When you go with dealer kits sometimes this happens unfortunately. But you have a warranty.
Not my bike so I wont comment on what I would do.
