2005 rough idle, sputtering at low speed

Any suggestions for a 2005 R1 with 24k miles that has a rough idle and sputters under 15 mph? The previous owner thought it was the after market exhaust but I since added a power commander, changed spark plugs, oil...tried to sync throttle bodies but the rough idle causes issues...He also had the exup valve removed so ima reinstall that but looking for other issues to check

Thank you and appreciate all help
