Air Cleaner Question
I was thinking of adding an after market air cleaner like a SE or Air Hog to my 103 Dyna. Do I have to get the FI remapped?
If I need to have the FI remapped do most HD dealers have the equipment to do this this incl. the map programs?
What is the approx. cost to have this done?

Here's the gig;
Air flow on factory bikes is limited by both the air filter and exhaust, the air/fuel ratio the ECM allows is set for required EPA values.
This is one of the first things folks change and is referred to as a Stage 1 upgrade.
You can change the Air filter or the Exhaust and no change to the ECM's AFR is needed because the air flow is still restricted by the other component.
It's when you change both filter and exhaust to more free flowing systems that something should be done to adjust the AFR.
Get it?
Changing one or the other is not a Stage 1, you need to do both and add a flash or tuner to reach a Stage 1 upgrade.

you should get it flashed for an air cleaner. The dealer will do a SE download for about 200 dollars...or you can get a vance and hines fuel pak 3 for about 300 which has 1000x more options than the SE download

Just curios, what "other components" restrict the increased air flow when a high flow air cleaner is installed?
