Default Anxious after broken vacuum to map line

Hi i'm a bit anxious here i was at the track yesterday and founded that i loose some power...Got to pit and test run the car to find that i was boosting at 13 psi but where at 14.4 AFR...I found that my vacuum line was shot.

I have a reverant build diypnp and was wandering if the diypnp is able to take back the timing to be ok with big knock...If yes how could he know that there where a problem ( maybe via the wideband sensor ? ) i read that our knock sensor are not very presise..

I didn't have a chance to change my vacuum line yet

Do you have knock sensing configured and working in the tune?
