I used the SE255 in my 2012 FLHTC and I was impressed. Like you I chose what I finally thought was best for me and quit reading after making my head swim over cam and dyno numbers. I narrowed down to the TW222 or the SE255. I went with the SE cam for the type of riding I do. I am no racer. I just wanted more power where I needed it for my two-up interstate riding and for passing. Do these cams work? Ask the Illinois State Trooper who surprisingly let me off with a verbal warning yesterday. He was second in a line of three cars yesterday on a two-lane road and I didn't see him there-unmarked car. I was up over 90 mph with just a throttle twist from 60 mph in seconds. He said he was unable to lock onto me and clock me and never had a driver of any vehicle pass him like that. I offered to tell him how fast but he declined. Good cop, good cam.

I think they should have this cam as stock cams on the big touring bikes but then no extra dough could be made. I guess I see why they wouldn't but I would have paid $350-$400 more for the bike. I mean if you are on the line installing cams in the motor doesn't matter which ones you stick in and if they added correct size pushrods, hey-great!! But....to me it was worth the change too.

No it doesnt. You either didnt ride the one with the 54's or you trying to justify spending the same money for less product. I can assure you that the 54 has the best numbers and the most fun factor. Just sayin...

The 48h has more torque down low, its intake closing is 29* on par with all the torque monsters, i.e.:
S&S 551 ( intake close) of 19*
RED SHIFT 525 18*
TW 222 34*
SE 255 25*
The 57h has an intake close of 38* and the 54h, 42*. So in the same motor, all things the same, you have to wind it up a little more to get into the torque band. I would think you should see max torque come on about 2500 and go to 5000 rpm. It would be nice to see a dyno sheet. A lift of 548 means its easy on the drive train, and the 222/238 duration isn't so much you got be wide open to make power. Dyno tuners mean alot, I went to a local one and he sucked, then I went to DR DYNO when I was in Laconia and it was like night and day. Ride it and see how it is. Torque down low is the way to go...

I did both builds myself and have ridden each bike. Not yet had opportunity to drag to see who comes in first on race day. I have had the opportunity to compare each bike from point A to point B shifting each bike at exactly 5K. The bike with the 48's crossed point B at 80mph while the bike with the 54's was less than 75mph at the same point. This was on an approx. 3% upgrade. The 54's may very well surpass the 48's in other instances. I certainly expect the 54's to produce better dyno numbers. If I were disappointed with my build, I would just change out the cams. I do my own labor and cams are not that expensive. I'm not trying to sell one over the other. My last build was a 95 inch softail with Andrews 37's and Big Boyz ported heads, etc. I know what a good running bike feels like. I wanted my touring bike to have more low end torque. I can just hop onto my softail when I want to stretch out ther rpms a little more. Just reporting my experience. Your mileage may vary.
