added true-duals headers - Remap?
I have a 2004 Injected Electra Glide 88TC. I bought the bike used, so I do not know the download that is in it. It had a SE air-cleaner upgrade, and Bassani Megaphone Slip-ons when I bought it.
My Question is,
If I add V&H Headers, can I get away with riding it with the settings for an SE aircleaner and Slip-ons for a paycheck or so (friggin tax season got the best of me)?
My concerns are, I am not sure of the download that is in it now. There is no visable hardware under the side cover(s) so I suspect it was a Race Fueler download. But that is just a guess. Heck, it may have nothing in it at all for all I know. I can say that it ran well enough, no hard starts, and only occasional decel popping, so I haven't worried about it too much.
I can say that both the exhaust ports did have some soot in them and looked healthy enough (not lean), the plugs look healthy too. In addition, I have about 5k on the bike since I got it without any problems.
Any help would be appreciated.
Thanks

RE: added true-duals headers - Remap?
Thanks, but this doesn't exactly answer my question so I will add a bit to my statement and question.
I am going to install a tuner, probably a PC3USB instead of a SERT (even thought the SERT is much more tunable) so I can do the work myself from home.
I intend to do my build in stages and do not want to pay for Dyno time over and over and over to have the SERT tuned- thus the PC3USB I can do at home.
When I am done with the build sometime next year I will take it to a dyno, but for now it is me, my laptop, and the seat of my pants.
The question being.
Do you think the tune it has now (for a A/C and Slip-ons) is so off from what it should be with the addition of headers to the package that it will be unsafe for the engine?
I will be picking up a PC3 next month, but I want to ride my bike and I think it should be okay, but I am looking for answers from those with practical experience.
Thanks again.

I dont think anybody can answer your question if you dont know what has been done to the fuel management system. You need to find out from the previous owner. Duals are going to lean your engine out.

Yeah, I know. I have been trying to convince myself otherwise. I guess I need to find out what (if anything the owner did), The problem being,I bought it through a dealer that says they don't know,norare they inclined to put me in touch with the prev. owner. As you can see, it kind of leaves me in the dark.
Do you know of aeasy (cheap) way to tell? I really don't have any ideas on that, do you?
Anyone?

SloChicken, My bike is carbed, So I would take the side covers off and look for any type of after market fuel management system.If there is not one I would say to be on the safe side you are going to have to invest in one. especially if you have your heart set on duals. If it was me I would give fuelmotto a call and tell them what set up you are going with and they will program a pc3 and you will be done with it. Cheaper than a dyno tune. By the way I have duals and love them.

RE: added true-duals headers - Remap?
SloChicken, obviously the safest course is to leave the factory exhaust on the bike until you can add the PCIII--I know, when I have something new for the bike I want it on the bike NOW.
I have an '04 EG, the SERT, and TD's (Rineharts)--and I know there are plenty of 14.6 cells in the fuel maps for the standard HD downloads for a/c and exhaust mods in the software--point being that you probably would not be too lean with TD's in the acceleration areas of the a/f tables, but probably would be at cruise (which is where the a/f is leaned out to 14.6).
Good luck.

Slochicken,
Technically, a big difference once you add the true duals. Once you remove the 'Y' pipe that is the stock rear cylinder header and put on the single pipe, you've changed the performance characteristics of that cylinder (like scavenging, back pressure, flow rate, etc.).
But to answer your question, you can continue to ride the bike without the tune for some time before the possibility of damage - performance suffers, but for areasonable amount oftime your motor won't melt into a puddle of metal.

RE: added true-duals headers - Remap?
Thank's all. I installed them today after calling V & H and actually talking to someone that wasn't trying to sell me the latest and greatest before hearing what I had to say. They said no problem, it will be fine until I install the PC3 next month.
So, on they went. 2 hours later I went for a quick cruise. Bike starts, runs great. Furthermore, the decel popping is now gone. Go figure.
Anyway, thanks again.
