I'm 16yrs and 166 tall im asian male i hit puberty around 14 and had a growth spurt since last year i have only grown an inch or less will i grow more

Perhaps: Once your bones have fused no further growth in height is possible. This usually happens in males around the age of 16 or 17 so you may grow a bit more.

Not much more: You seem to be in late puberty and your growth has slowed in the past year which is normal. My best guess is that you will grow perhaps another 1/2 inch and there is nothing that would help you grow more since your growth plates are closing
