I can't ride a spec sheet. I have ridden a bike equipped those cams though and I like em quite a bit better than the 255's. Seem to be snappier and the sign off seems to come later. Maybe it's tuned better than the 255 equipped bike. I'm no tuner. Maybe all those years racing got me to care more about how things run and less about specs.

I can't ride a spec sheet either but the OP said he wanted more power not low end TQ.. What you say about Specs, is still better than what happens reading the internet.. I've gone both directions mainly to amuse myself with baggers.. Tried what was supposed to be an internet high HP 95 ci build with a certain cam and got only mediocre results, went to a cam I new would make HP and it did. Changed from big port to smaller ports and picked up 5-6fp down low and lost 3/4 hp up top.. End up with a smaller cam still in the 40 degree range and it's been in that bike for 20K-25K.
Again because of Internet suggestions I did a 103 with 570s and hated the low speed performance (over exhausting) so a dropped to a W5.. Much better but too mousy for me.. Syke SP232 did a bunch better throughout the whole powerband.. Traded the W5 for a W777 and never looked back.. This is running only 9.9 to 1 cr...
Now if you want to make power from 2K to 3K above everyone else.. The TTS100 is the cam to chose. Not sure about the sign off.. I would compare dyno runs for the same bike on the same dyno and tune..
Here is a cvo comparison and the TTS kills the 255 up to 3K.. After that they are the same.. Build info on the websight.
I don't know but for a 2 up rider 99% of the time(his words not mine), it would seem to me that hitting 100tq 500 rpm earlier than most any cams on the market would be the way to go. What camset for a cam only change would you recommend for his riding style, not yours, lol.

Did I recommend a cam???
Nope.. Only stating my personal experience on what I like.. Need more information before doing anything.. I would definitely say if the guy wants more power, he needs to look elsewhere then some neutered cam that peters out.
The hitting 100fp for a 2 up ride is a fallacy.. If you really want more than a 1000 rpm spurt, you'd better find something over a broader power range and learn how to use that little *** sitting above the left floorboard. You have to use that **** if you want to go faster anyway..
Add.. It's certainly possible all he wants is the kick down low.. After all the discussion started second hand.. He asked for power but maybe all he wants is the kick down low..
