The track is a pretty decent size setup, i am running a 10.5t and my esc is mildly turned up...Does my gearing seem okay?

the chart I have shows them running around a 8FDR
You are at around a
22/87 = 10.26 FDR
23/87 = 9.83 FDR

how big is the track? I ran a 25/81 on a 13.5T and it moves pretty good on the track I run on but it is a small track.
