Ok found it its at

// Custom M code points
#define CUSTOM_M_CODES
#ifdef CUSTOM_M_CODES
#define CUSTOM_M_CODE_SET_Z_PROBE_OFFSET 851
#define Z_PROBE_OFFSET_RANGE_MIN -15
#define Z_PROBE_OFFSET_RANGE_MAX -0
#endif

had to change them to needed values.

only problem im having now is the printer probes the bed before printing but when it does its second prob it only probs the middle( didn't do this before) and starts printing and is definity not reading first probing values as a big print had obvious low/high bits on bed.
so obviously it knows its boundary's for probing just doesn't read them for some reason. i guess another day another problem.
