Never felt like my 96"/255 combo "died" after 4,000 R's, still pulled harder than the stock cams, just not as hard as some others. I now have 103"/Andrews 54H/Big Boyz heads combo and it does pull much harder above 4,000 but, I seldom hit it that hard (but when I do, it is fun! 
). I usually ride in the 2800-3000 RPM range because I like being in that power band and I know I ain't luggin chit, the 255's work great there! Wish I still had the 96"/255's and the extra $$ back in my pocket. My

Just don't see it.Bought an 09 ultra I came off a 72 shovel,My 09 I did 103 stage II 255;s had some mild headwork done, notice when hot starter hit pretty hard. decided to trade for 11 limited upon suggestion started to research 254's came across this forum and started readin the 255 bashin and this dyin at 4000 rpm etc.etc. I dint have a tuner just a canned map from harley didn't know any better, before I traded itook it out and ran the p$$ss out of it I just don't see it, when the tq is fallin off the hp. is comin on maybe my *** just ain't as sensitive as others when it comes to seat of the pants or maybe these guys are goin by what they see on paper. But IMHO its a good lowend cam for everyday normal bagger geezer glidin practical ridin. don't get me wrong I like to get with it just like the next guy but I guess its not on the dragstrip.

It needs to be also stressed that the OP has a stock 96" engine, and if he puts almost any other cam in that bike without a compression increase he will lose low-end performance. Exceptions would likely be the Andrews 48H and the S&S 551 "Easy Start" cams. If he doesn't mind a loss of low-end TQ and wants the emphasis to be at high RPM's, the SE255 cams are not the right choice for him.

Are you for real....? 4000rpm....255s will pull to 5800 i have the dyno sheet. I run it up to the redline at 6000 all the time if i have to win a race. Put them 255s in. Mine pulls from about 1500 all the way to redline...Look at my tag. A good tune help also. I have no ping at all in any gear now. Ohhh yes there are better cams out there for sure, but my bike is still under warranty thats why i went with SE 255s.

No body "runs" along at 4000k but I run mine past it every time I am out!! I want power when needed!!! 255's DO NOT SUPPLY ANY POWER PAST 4000k ish rpm......if you drive like a grandpa and never want to hear the wonderful note of yer pipes then its a perfect choice.....but for me there worthless........... .02
FWIW, the shape of this TQ curve is what I want, and that's flat. It has no major peaks or valleys and just provides good power all the way out without a pronounced "band" or peakiness.
BTW the top horizontal line on the X-axis is 100.

Real life - i use my entire RPM range. I run to red line at least once a ride. That's what the engine is made for - running.

My setup is a beast.
255's with a PC-V and auttuner with good intake and pipes (ported Throttlebody).
I never feel it fall off. It will max the speedo in 6th gear no prob.

I know I'm preaching to the choir here, but there are "better cams" for what? Peak-HP? You're right. Are there better cams for increasing low-end and midrange TQ without other engine mods beyond normal Stage I upgrades? If there are I'm not aware of them.
