Not mentioned is that there are two SE Tuners, the street and the pro. dealers liek the street model because they can sell you a dyno tune with it. The pro version is stand alone OR with a dyno. Make sure which you have. stay away from the street version as it has limits which the pro version does not. Power vision and TTS are also on equal to or better depending on what day of the year it is.
dont understand what i am reading but I think you mean dealers do not lke the street because they cannot sell the dyno tune but they can with the pro version. The street tuner has very limited maps and is only good with HD screemin eagle components and their is very little that can be changed with it. The pro lets the ecm be recalibrated and changed for build specifics and requires a trained tech to fine tune and tweak the map that is available for the build. TTS is a fave of mine and at any time you would have a problem, if it was done correctly, you could always put your stock map back and get assistance from the master himself. Steve of TTS was the original SE tuner developer so he is very capable
SEPST, TTS & PV have similar features and all work equally well with some stand alone features. Currently the PV seems to have taken the lead.

Thanks again guys. So, the harley tech can use the tuner despite not have the Dyno. I will cough up the cash and make the purchase. I will also call the Dyno guy and see if he will make a claim as to how much better he can maximize the output of the build. Anybody fell strongly in recommending going to the 103" at this time or I am going to get relatively equal performance from the 96" stage 2l?

HD SE 255 performance Cams p/n 25638-07
Aside from the two quotes HD is a bit vague on specifics re: compression release. Claims "substantial increase in low-end TRQ on engines with compression up to 10 to 1": "Compression releases may be required depending on displacement and compression ratio". My buddy did the same Stage 2 on build his 07 Ultra, also included the 103" BB; but, without CR. He had problems with warm starts.

also I see you going from a stock motor to several upgrades at the same time while looking at cost efficiency. are you able to do any of this yourself? I would suggest put on the AC, slip ons optional and get the tuner of your choice and do some street data gathering to dial in the VE corrections. The timing will already be more aggressive as soon as you load the starting map. You will notice a great improvement over stock and cost effective. Then if you want more add the cam of your choice, etc
IMHO, just saying that adding it all will of course make a dramatic difference over stock. why not finish a stage 1 and ride it to know if you want more and where first. why leap frog a stage.

Hey 1Cannuck; appreciate your information and the suggestion about doing Stage 1 myself, then adding cams later, if desired. This has been in the back of my mind as I have the ability to install the slip ons and AC. Although I am computer litterate, taking on the tuner will definately be something new. I assume when plugged in I will get prompts to select a map containing the specific components of my build/bike. However, I will be lost as to how to go about making fine adjustments to fuel etc...Stage 1 might offer sufficient power for what I am looking for. It will also minimize my cost.

plenty of info here and the place to ask for whichever tuner you choose. I went with the SEPST but agree that TTS or power vision are just as good. once you pick your tuner do several data runs to tune in the VE before you touch anything else. The Sepst thread provides some good AFR suggested maps provided by pro tuner.

Very interesting....
I have an 09 Ultra. I have made many changes to it as time has gone by, some I would recommend, others I would not. I'm envious of you, having a "clean slate" to start with and so much knowledge, experience and parts options available that I did not. But be careful. The road to "more" can be a long and winding one. SE 255 cams in a 96" motor work really well and are a good choice for an appreciable increase in seat of the pants performance. Also they can be had off e-bay much cheaper than any other option. Having said that I would rather have the Andrews 48's because they perform very well in a 96" and leave room to build on if 103" seems like the next step in progression. 255's in a 103" work but they require compression releases. Problems arise without them. Ask me how I know! The Pro Tuner is a good choice for a flash tuner (I have one) and are widely recognized through out the tuning community. Having said that, I believe I would rather have the Dynojet Power Vision. This is based on it's operator interface is much more intuitive and easy to use. Furthermore, my tuner no longer uses his Pro tuner in favor of one and I trust his judgement completely.
I'm going to add this because you may be wondering what I might do if I had the chance.

After much research, I see this as being every bit as good an option as any other keeping results and cost in mind. Good luck sir!

Holy cow; I've not seen Dyno results like that before!!!
Thanks for chipping in my friend.

For any who were kind enough to give me your advice late last fall I want to take a moment and offer my results. I had my build completed by my dealer during a very harsh Canadian winter. Kept the 96" but did SE A/C, slipons, tuner, and 254e cams. I got to try things out twice last weekend: here are my first impressions:
- no trouble with compression (i.e.) hot starts
- no hesitation, flat spots, decel popping etc...looks like the SE Tuner mapped the changes
- love the pipes; low deep rumble, growls when you get on it but are quiet HWY cruising
- clutch has a firmer pull I assume do to the new spring
- only modest performance gain in the 2,000 rpms range but the thing pulls real hard at 3,500 through 6,000+. I backed off there so can't comment beyond this point yet.
- Long hills are no longer a power problem
- Now I can pass as many cars as I want, when I want!!!!!
- seems the 254es perform true to the chart HD used to have on their website...where did they go?
This build was worth the effort and money. I will reply if anyone has any questions. Thanks again
