Default torque dip? dyno sheet (pic)

What would you guys recommend to help cure this dip? The bike is setup for more mid to upper range riding. It does pull pretty good on bottom and the throttle response is awesome, but just looking to see what I can do to improve it just a liitle. Any suggestion?

You were definitely making more torque earlier but what changed between the two pulls? Was that just the tuner?

I actually swapped cams. I originally had the bike set up for more low end and found myself wanting more on top. The build is actually all SE parts with the heads cleaned up a little. My builder/tuner was actually surprised on what I put out in #'s because of the pipes. He hates the BR and is always trying to get me to switch to the fat cats! LOL! I picked it up yesterday and put about 30 miles on it and it feels like a whole new bike. Even with the torque being less than what it was, it still pulls just as hard as it did. But looking at the sheet with the torque being lower I would have never guessed it.

Believe me, I hear that all the time! LOL! The fatcats are the pipe of choice around here and everyone just hates the big radius, it make me laugh!

Thanks for the clarity Red. I think. I don't catch all posts/threads

but is this a 103" pieced together?

I'll bet ya don't even feel the dip when ya whack it!

Usual suspect for your dip is pipes, but I'm sure you love em soooo...

Run em!!!

Looks fun @111/112.

Do you have a a/f reading? What do you have for a tuning unit?

There is only 13 runs between (before and after) the builds, thats not enough time to tune the fuel and ign.
