Street Scrambler 2021 + Vance & Hines Full System Issues And Mapping

Hi there,
I've just installed a Vance and Hines 2 into 1 full system and a Dna air filter to my Street Scrambler 2021.
Did 12 minutes adaptation and the bike rode perfectly for a couple of days.
I then couldn't ride it for a couple of weeks, tried to start it and it couldn't start, like low battery. Charged the battery and it start but now I have a engine light on!

I've just purchased a ObdlinkLx and Tune Ecu to be able to check the error code plus my idea is to load the Street Twin Vance and Hines full system map (30058_04) hoping that it would perfom better with the mods.

Question is would the street twin map create issues to my modes? Like what would happen to my off road mode as the street twin doesn't have one?

Thanks guys
