SO to SUM it up, yes it is confusing. You may be good with a D/L, you may have to get the SERT, but to say that no kidding every bike HAS to get a SERT is NOT CORRECT. I would suggest this. Before you do a Stage one, take a look at your plugs. If they look great, your bike is probably not on the lean side, and you should be good with just the D/L. If you are lean already then you may want to go with the SERT. ( Jamie I would bet your bike was running a bit to lean out of the box, and if the D/L still was not enough to get into a good place) If you plan on doing more engine work down the road after the Stage one, go with the SERT either way.

1. Bike ran great stock.
2. I added the SEII slipons and noticed it was lean (flat spot in RPM range)
3. Got the download and bike ran great.. better than ever.
4. Added the SE/AC and the bike is back to being too lean.
5. I need a SERT (or a PCIII, DFO, etc)
I used to race bikes. That doesn't make me any better than anyone else, but I think it might make me a little more sensative to a poorly tuned bike.. I'm going to get the SERT, but I think some people might ride my bike and not even notice the problem. It's not like it's running terrible.. if it was warm outside, I'd be out riding it today. I just want it to run better and the flat spot nags at me each time I ride it. Like I said, I think I could probably leave it as it is and not have any problems. I'm concerned about it running hot when the weather changes.
By the time you pay for labor, the download is almost $200. A SERT is only $170 more IF you are capable of installing it and tuning the bike yourself. I'm sure it's quite a bit more if you have the dealer do it all. For someone who doesn't have any money issues, I'd recommend they get the SERT right from the start. If you are capable of doing your own work, I recommend the SERT right from the start. If money is tight and you can't work on your own bike, then try the download and see how it works. Each bike is a little different and you might be happy. Worse comes to worse, you can always put the stock AC back on and it'll run perfect with the download.
The only thing I disagree with is the plug reading advice. It's good advice, I just don't know if it's possible to follow. Unleaded gas makes it difficult to get a good read on plugs. That, combined with the bike possibly only being lean in a certain RPM range, makes it even more difficult to use the plugs as a gauge. You can listen to the exhaust note and get a decent idea... if you've got a smooth, even, exhaust note that suddenly changes to a stattaco sound (almost sounds like a miss, but not quite), then evens back out again as you climb through the RPMs, then you're probably hearing a lean spot. The spark knock sensors take effect during the lean RPMS and retard the timing, so the sound of the exhaust will change and you'll notice the bike isn't pulling quite as hard as it should be.

RE: Exhaust for 2006 DYNA
I agree with you man. You were not the one I was saying was ranting and raveing. You are right about the plugs, you can only get a overall picture from reading them. Mine are a tad on the lean side, but nothing that is gonna hurt anything. And I am not haveing or at least noticing and flat spots in the RPM curve. I know exactly what you mean. And I hear you on being more sensitive to a poorly tuned bike. I do know that you can take to stock 06 Dynas and one will be leaner than the other. Thats why I beleive your bike may have been on the lean side from the get go. The SERTwill set ya straight.
I have a question now, when they do the Down Load, does it adjust to your set up, or is it a strandard map that they enter? I beleive its standard, but if it is not, or it can be tweaked at all, could that be your problem? Since you did the AC after the download? I dont know, I am just brain storming.
As for the temp, i do some desert riding, and it gets pretty friggin warm. That may become a concern for me this summer.

you get a very good picture from plug reading plugs if you know how. and you can take plug readings from multiple throttle openings and load conditions. afr, timing, heat ranges are all indicated. as far as one bike being leaner from the factory than the other, with the standards set by the engineers-------do you really believe all that?

RE: Exhaust for 2006 DYNA
Hey Boys I just got my Street Bob today (a month early) and following MAGAHDMAN advice I'm going to do the Cycle shack slipons, New AC, and SERT tune. I've been away from harleys a few years after owning many over the past 20 years. Before the FI motors i used to have the skill to work on my own bikes but nowaday with the FI I'm a bit lost. My question is this, will I be able to do these mods myself with very little trouble or should I have my shop do them for me? I just want these mods to hold me over for 8-10 months while I plan my 98' build for later down the road. Thanks.

JAMIEWG. Thanks for the reply. Do I need to use the laptop out by the bike or just to download 411 into the SERT?
