在post meta中添加post后的acf

I have added post meta to my CPT.

In that CPT i have also ACF that add fields to this CPT.

I also used the hook save_post{post_type} so that when my CPT is updated, meta is added to that post.

My problem is that the ACF data is saved AFTER the add_post_meta function runs and i need the add_post_meta to use fields from the ACF so i need the ACF to run first, then the add_post_meta function will get it's values acording to calculations by these ACF fields.

the code i used is:

add_action( "save_post_car", "save_posts_meta_values", 999999, 1 );

function save_posts_meta_values( $post ){
    if ( get_post_type( $post ) == 'car' ) {
        $post_id = get_the_ID();
        $my_values = array(
            'front'     => 5,
            'back'      => 6,
            'right'     => 7,
            'left'      => 8,
            'engine'    => 9
        );
        update_post_meta( $post_id, 'total_values', $my_values );
    }
}

can't come up with a proper solution to my problem.

i have searched through the stackoverflow website to find similar questions but the didn't come up with the solution to my problem.

please help :) thank you!
