I have an 01 Roadglide FLTSEI and I want to put the thunderheader on but want to use my Boom Cans. Im told that I will not need to remap because the 1550 has the highest map setting stock. Any suggestions.

You lost me with your choice of words, but then I'm getting old. Are you talking about a Thunderheader 2 into 1 exhaust system?, mufflers only?

Don't understand about whatever Boom Cans are either. I always thought they were mufflers. If so, your question don't make sense.

Regardless, with the EFI system you have, it's a fairly safe bet that you will probably have to use an aftermarket device like PCIIIR to help tune your setup. Whoever told you the info about remapping was probably referring to what is available from HD not aftermarket.
