Scrambler Street Scrambler Mods

Hi all, just installed this legendary exhaust plus a DNA filter and bar ends mirrors. Bike is now looking really good and I'm wondering what else I should change on it...

After the install, the bike shorted a couple of times when I was trying to switch it on (resetting the clock), also in another instance, while warming up, at the flick of the throttle it couldn't sustain the revs and wanted to switch off...so I did restart it and went on at idle just fine ‍‍♂️
I don't know, perhaps the ECU is still learning the new changes.
Haven't remapped yet, would it be worth loading the street twin map for the vance and hines? It seems available on TuneECU...

Thanks in advance.
