Piping not nice and tight to top and border

[Edsbear]

Hi, any tips for getting leather piping nice and tight to top and border, just can’t seem to get the stitch close enough.
Piping is 1/8" nylon, I tried 5/16" and 1/4" piping foot but the piping still doesn't seem close enough
Making a car seat cover, luckily just using scraps of leather at the moment

Thanks

People can maybe pickup what the likely small problem is with little more info ?

what machine . Maybe give Pic. of your inner/outer press feet set-up on machine also . Is this a compound feed, or a drop feed walk ?
