Okay. I have a 2004 FLHTCSE Electra Glide. After some thought and dyno test research (not on my bike) I decided to stay with the stock HD headers and slip on some Rinehart mufflers. Same ones that come with the true dual set up but with stock headers. Took two months to get them as they were on back order.I have a race tuner version 4.12 installed on the bike and a high flow SE intake. So now I want to dial in the map. I read the manual (that took awhile) and I am really interested in learning more. After looking at the maps that came with the CD I think the closest map is 105HX021 but it is dialed in for SE mufflers and I think the Rineharts are a little more open (they sure sound like it). The bike runs good but a little popping when I am up in the RPM bandon decel. I have contacted HD Maps and they are getting back to me. After reading some of the posts on the forum it is apparent that there is much knowledge here. I am willing to learn, willing to fail and willing to listen. The question is, should I go with a download from HDMAPS or tweak a download that I have on the disk, maybe the 105HX021. I really want to learn this stuff and will listen to what the experts have to say. Perhaps some of you have allready done this? Maybe with a similar muffler, say Samson (that's what the bike came with)or Vance and Hines. Thanks in advance for the help! Willie

Willie
the 105HX021 is the perfect fit. That download is for all free flowing mufflers. It should work perfect.

 

rmarion. Thanks for the reply. I thought that was the case and since you verified it I will give it a shot. Thanks again. Nice bike!

 

Marion: The upload worked great and I wanted to say thanks for the input.

 

Willie Great to hear............

Enjoy...........
