I understand that a stage 1 upsets the EPA tuning the factory is required to have, and a tuner box is almost a requirement for it to perform modified.
I could be off on that, but that's the process I went through with the stock to stage 1 on my 2010 FXWG.
I'm confident it's a relatively simple fix for you- it's a fuel mixture or electrical and not mechanical, which is $$.

If it turns out you need a tuner, there's some great source topics on the HDF.

You mentioned you just changed the plugs. Did you buy the correct plug for the bike and check the gap before installation? .038"-.043" or .040"

Do you mean change the gap? Because the spark plugs are brand new
