Tephra / Spark cut patch not working

Recently got Tephrav3 56910309 rom and have been messing around with the launch timing and fueling maps. however i noticed in the logs that adjusting the timing and fueling does nothing. my timing stays mid to high 20s and fueling stays above 14.7 AFR. I have the factory 2 step limited set to 6k and the spark cut patch set to 4.5k.
Is there anything Im missing that those tables arent impacting my launch values? like is there a setting i need to enable in the tephra rom?
