Hey all,
I just got my 4" Rinehart true duals in for my new to me 13 Road Glide Ultra and I'm itching to put them on, but I'm not sure how bad of an idea it would be to do it without any kind of retune yet.

I'm going to get a PC, but I'm waiting till I get my new air cleaner so I can get it all at once.

Thanks for the help!

 

In my personal experience as long as you don't do the AC you should be ok. Once you do both you will need a tune.

 

It will run fine, just not going to open up all the potential until the stock EPA tune is gone. You will really want to wait to do the air cleaner until you have your tuner.

 

If all your changing is the pipes, you'll be fine for now.

Of course it will run better (and you'll be happier) with a tune.
But your not going to ruin the bike without a tune.

But if your also changing the A/C, then you'll want to get a tune right away.

 

Thanks for the replies. That's what I figured but I haven't dealt with the newer bikes much yet and wanted to make sure it wouldn't run it too lean.

I'm still used to my finicky M&M EFI on my Road King. Every time I changed the way I sat on the bike I had to get my PC3 retuned! Haha.

I plan on ordering my PC5 from Fuel Moto preloaded once I order my AC and install them both at once.

Now I just have to wait for the bike to cool down enough so I can get started on it!

 

Bad advice. If you install true duals, you will need a remap. If you are only doing slipons, not needed.

 

I agree. The true duals will change the tune requirements. They need to be richer in the low to mid range. The AC needs to be richer in the top end area. You can put the PCV on without the AC, just get the tune for it and the true duals and you will be fine until you do the ac too.
