2015 xp1k runs rough off idle

Anyone ever seen a 2015 xp1k car run rough at part throttle and at lower rpm. Has 200 miles on it now, but has do e it since 0. Runs fine with a bit of throttle or at higher rpm in a load, but under no load at light throttle, is I’d very choppy, almost missing, and honestly don’t idle really smooth. I have three other friends with new xp1 cars and they are smooth. Quests ill be taking it in for warranty work already unless I find out its something simple. I will try plugs but doubt its that. Maybe an unbalanced injector, or jumped tooth on cam? Runs great everywhere except lower rpm and light throttle.
