Dropped the bike at HD last night.. they worked on it last night and most of today. Road it home in the rain, so didn't really get a chance to "run" the bike to see how it performed. Hopefully this rain will stop for a day this weekend :-(
So, this was the cam change (SE 255's) on a stage 1, 07 Ultra. It included a dyno tune, the dealer's dyno is a SuperFlow WinDyn (This dyno is generally 10-15% lower than measured on a DynoJet for the same bike). Because of the differences, I had them do a baseline run prior to doing the mods/tune.
The results:
Before mod: HP = 65 @5500 rpm, TQ = 79 @ 3600 rpm (stays above 70 til 4700 rpm)
After mod: HP = 74 @ 5500 rpm, TQ = 88 @ 3200 rpm (stays above 80 til 4700 rpm)
Corrected to the DynoJet, this would be about: HP = 82 and TQ = 97 - this is a little better than I'd hoped for, especially the gains in HP.
I've attached the SuperFlow chart. I think it is a pretty good curve. ATR is at 13.4 until cruise which is set around 14+.
07 Ultra, SE A/C, SE II Slip-ons, SERT and now SE 255 cams

I have all the parts to do the SE255 CAM swap and the SE Compensator at the same time.
Here's what I want to know if it is a good fair deal:
I was at my dealer today they offered me the following. They said they would do my 5000 mile service (me providing the Amsoil), 3 Baseline dyno runs (before Cams & Compensator), Install the Cams & Compensator (with me providing the parts), and do 3 more dyno runs for $550. I have $495 in all the parts right now, so for $995, I would get a 5K service, 6 dyno runs and all labor. Do you think this makes the pot sweet enough to let them do it?
My thinking is that they will be more likely to honor any furutre warranty claim I may have (providing no foul play on my part) if I throw them a bone and get the work done by them. Normally they just see me at the dealership for parts I can't find cheaper on the internet, this would build a little bit of repore with the service department.
What are your thoughts on the matter?

NAUIdvr1, It's probably a fair price. When they did my install, they included 5 hours for the cam/lifter and oil change, did a baseline run and then a complete tune. HD put in 2 hours for the dyno, but probably spent 3-4 hours on the dyno and only charged me for two hours the tech's time (no dyno time). The normal dyno tune is $240+tax but HD only charged $112. However, I had worked with the owner to get this price, so it was a DEAL! btw, I do all my service work with them, so have a pretty good relationship.
I think it was necessary to do the complete tune after the upgrade. They wound up doing a lot of low rpm work to set up the proper throttle levels. On the initial pull, my AFRs were set at 9.0 max. This was way too rich and in fact, I had noticed that my MPG was pretty bad. After the tune, my AFRs were 13.4.
I don't know how happy you will be without a tune... do you have good maps for the change? iclick said he's was pretty much right on, so a tune wasn't needed. Others have said they didn't have good maps for the change and needed a tune to get it running correctly.

I am attempting to aquire a map or two from those that have a similar 2009 FLHX setup to mine with the SE 255 cam's installed (SE Heavy Breather & Reinhart Slip-ons). I think that a tune would definately be necesssary after the work is completed, hence the 3 dyno runs (or tune if I want it). They said if I had a good map, to start off with, I could use my PC-V with Auto tune modules to play around with it, then bring the bike back for a run on the dyno when ever I felt my tweakes were on the money or whenever I wanted.
P.S. So if anyone has a map for a PC-V for a 2009 setup similar to mine, with SE 255's, and would be willing to share, I would be appreciative (PM me if you want to discuss $, helping you pay for that map would only be fair).

Don't know if this helps or not. My 2007 FLHT has the now discontinued SE Race Tuner and is prior to throttle by wire. The tuner started out with the canned map for the 103 inch motor with the SE 255 and adjusted it to my stock 96 inch motor. I thought that was interesting that he didn't start with the canned map for the 96 inch stage I motor and work up.

I think the tuner got it right, as the only difference between the TC96/255 and Stage II is displacement and compression. I would think the Stage II map would be fairly close, and much closer than the stock map. The cams somehow fool the MAP sensor and throw off some AFR's, mostly in the cruise range I think, so since the Stage II map includes the cams I'd bet on it as the best starting point.
