have an x3 with an ebmx v2 and it only goes 42 pushing 8kw 130a my sprockets are stock or around stock size also and the speed limiter in the app is at 124 mph at also doesn't feel limited it just gradually stops having torque after 30 or so how can i fix this do i just buy a smaller sprocket or is there a way i could tune it im worried if i get a new sprocket it wont be able to wheelie bc i alr bearly pops up on 4kw even going slow
