I know the cam. Your ultra is a 96", 103" or 110" and in all cases without raising the compression you will be taking a torque hit under 3k rpm with that cam as a direct bolt-in. True duals and then you take hit number two. If you start from square one and optimize the compression, the head ports, and pipe you can recapture some of that torque hit and then it will walk away from the stock cammed bike after that. Just remember the 07 bike has a very tall gear ratio and we ride mostly in the 2-3k area, a torque hit there you will feel and there will be more gear shifting required to stay in the power band. May not be a lot of fun with a heavy bagger. 6th gear becomes not too useable until over 70.
Read the posts here and look at the cams they typically use.
The seat of the pants power that most want and have fun with is a rise in torque right in the heart of where they ride most. Plan for that and you won't be dissapointed.
As a side note I have a friend that lives in Orting that had that cam installed in an 08 SEUC along with Rinehart TD pipes and he made them pull it out and return the bike back to stock. Not a put down on the cam but more about misapplication or perhaps a tuning issue as well. That cam and the TC26D have their place and can make good power but the rest of the parts need to be set up properly and a very good tune or the result may give the impression of going backwards.
