When to shift stock 99 accord automatic/manual?
 

i have a regular ol 2.3L 4cylinder 1999 accord and it is automatic but i can shift through all gears without a clutch manually, i like to when i wanna have fun and let the vtech do its work but i dont know when i should shift it
i leave it automatic in regular driving and i let the rpm hit around 6.5k when i want to have fun. is that a good rpm? and ive heard that its bad to keep it in 1st for high rpms so ive been shifting to 2nd at 3k
