I love the cams also after my duel with getting them installed but man what a difference! It really does pull hard! I went for a 300 miler yesterday up Pacific Coast Highway 1 from Pismo Beach to Monterey with the wife on back holey smokes! You can run 6th gear a lot lower than the manual suggests not that I would do this often but it will pick itself up and leave from only 50mph. Milage sucked at first about 33mpg then I installed the Auto Tune and iclick helped me out this weekend and she runs even better. SO WHEN THEY SAY A GOOD TUNE MAKES A DIFFERENCE IT DOES. I got about 38mpg at 75 to 80 mph and a little better if 65mph and under crusing. Noise yes the ol Rineharts are barking quite a bit lounder and you can tell a little lobe at the idle shesounds great man!

I finished the install of SE255 cams a couple months ago. I used TTS Mastertune for the fuel map. Street tuned it myself with Vtune and then had the WOT areas tuned on the dyno. This gave me a very strong running bike. The WOT tuning gave me another 5 points on HP and torque from where I had it tuned with just the TTS street tuning. Crusing with a light throttle, I can still run 42mpg @ 65mph, 2700rpm
Here is the info on my bike:
07 FLHTCU
96ci.
TTS Mastertune (starting map PS176-002 with 96.7 ci displacement) (Street Vtuned)
K&N RK-3910 Air Cleaner kit
SE 255 cams
09 FLHTCU Header (no cat's)
08 CVO 4" slip-on mufflers (cat's & fiberglass removed)
Jagg 10 row oil cooler
SE compensator primary sprocket kit
SE heavy clutch spring
Final drive ratio of 3.06, Andrews 30 pulley, 68 rear drive pulley (final drive ratio of 3.06 vs 2.79 stock)
Street Vtuned to 80Kpa, blended out to the right and down.
Then dynotuned for wide open throttle only, but cruise checked.
Tuned in 4th gear
79.69 HP & 92.06 ft-lbs.
The 09 stock header and mufflers are the restriction.
It pulls strong from off idle up through 4500rpm, just where you want torque.

Add me to the happy list. This cam was all pros for me except exhaust noise, which is elevated a tad more than I would've liked. To be fair, I expected it, and any performance cam will do the same. I do not hear more than a tad more valve-train noise, however, much less than I expected. I marvel at the feel of the bike every time I ride it, as this is the way it should've run from the factory. Tons of usable torque between 2000-4500, right where I ride.
Gas mileage? About the same as stock for me using the PCV with Auto-Tune, ranging from 37mpg city to 50mpg at a slow, steady cruise. I can't quite do 50mpg with E10 gas these days, though, as that's all that's available here.

I was going to install the 255s I found on Craigslist. Changed my mind.
Decided to do a 103 big bore kit. I have a set of 255s that are 500 mile take-offs. They look almost new.
Anyone want them? $150 plus shipping (what I paid).
I can send pics if you want. Just PM me.

I agree with Iclick, this should be the stock cam in this motor. BTW: I was running with a 110 guy this weekend. He is thinking about upgrading his cams now because I was running too close to him for comfort.

Loving the torque! The dyno sheet really rolls off over 4k RPM, but the butt dyno is real happy.

I agree, it's like having a sleeper! My Ultra looks and sounds almost stock, but easily runs with the 103's & 110's. The pulley changes help with this too. The exhaust is a bit louder with the cams, ever so slightly loper at idle. If you're willing to be louder, there are guys getting 100 ft-lbs of torque with the D&D 2 to 1 header, muffler and the right dyno tuner.
