It will get a little louder when you remove stock head pipe catalytic converter.
That is what I like about the e-series mufflers. I am currently running 14 discs with the stock header. When I install the 2-1-2 header I will reduce the number of discs to where the sound/performance meets my needs. Win - win in my book.
Jamie posted it I will not be able to find the post. But he mention that he/they We're working on dyno jet tunes before he did his own for the 2014 year. This was back when we were all waiting for the power vision to work on 14 Rushmore. I have seen him mention here and there they do some RD for Dynojet. I just this weekend grabbed a 617 calibration off dyno jet site and switche'd from my 614 calibration. If you put in model year 2015 it come up with tunes named 14-15. When I put in just 2014 year it come up with 614 calibrations. this was for touring models. I read lots of stuff in here I appreciate all of you who post.
It's somewhere in the middle of that very long powervision thread in the EFI section. I can concur that I did find a post by fuelmoto basically said someone's tune they got from dynojet could have been DJ's own tune or could have been fuelmoto's, basically implying that fuelmoto know's that DJ has their tunes and distributes them.
In an effort to un-hijack the thread, I will comment on the original topic. I originally used the DJ stock improved and then got a FM download for my setup. I took the closest DJ tune to my setup and did a compare and delta. In total 10 tune items were different between the DJ and FM tunes. Now, I cannot say which is better as I did not run both on my bike, but just that there are significant differences between the two.
Here is the AFR delta as an example:

Much of the data and bike testing is shared between us and I have developed quite a few of the Dynojet maps, I built their 2014-2015 maps at their R&D facility. We also purchased 2014 & 2015 bikes here for testing and fuel map development

Fuel Moto develop's maps for Dynojet, however in most cases they are a bit different even for the same application. For example we may have different AF targets & ignition timing etc...

Cool, thanks for sharing!
I can tell already looking at that delta that it's the difference between the stock target AFR table and the one that fuelmoto (from what I've seen) uses.

Well that clears it up then! Thanks for commenting.
The S&S Web site has pv maps to. The trick is when doing search fields do not be to specific. Just put basic bike model and it brings up tunes. When getting to specific no tunes showed up. They have basic stage one tunes. I discovered that when looking for basic 617 calibrations. I still chose to make one from Dynojets downloads and the 614 calibration I got from fuel moto Based on my awareness of fuel moto involvement.
Alright I've got my "dirt cheap" exhaust on (full exhaust, true duals for under $300. I wrote about it over here if you're interested) and I'm all ready to start doing some tune scrutinizing but I'm realizing that there's no tunes up for grabs for full exhaust with the stock air cleaner.
So for the time being I'm running at tune off DJ's website meant for V&H true duals with V&H HO mufflers and a stage 1 AC, and I'm autotuning from there. I'll do that until I'm consistently in the 3-5% range and then we can take a look at what changed.
I also filled out a form for fuelmoto so we'll see if they have anything in their library for what I'm running.
In other news I read through the PV materials and apparently autotune can also make timing adjustments. That's very surprising to me and I'm not sure what to make of it. When you're tuning timing on a dyno you've ot the dyno controlling your rpm, you control the kpa with the throttle and then you're looking for minimum timing for best torque in that cell. The PV can't measure your torque. One of the shadetree ways that some street tuners use is bumping timing until you get knock counts from your knock sensor and then backing off a couple degrees. Advancing timing until you get knock is somewhat... abusive is the best word I can think of right now.
That isn't to say there isn't some other method DJ has come up with. I've got to give them credit that their method of fuel tuning using narrow bands is pretty clever. They may have another trick up their sleeve for doing the timing. I'll keep digging and I'll just ask them if I can't find any documentation and see if they'll spill the beans.
