need some some help

i hit full pressure and my engine shuts off, why ?

on log 195 sec in to log.






the engine starts back up , i had a lose connector on my water/meth. the knock is now down the 1.5 and below. but still shuts down. it acts like i am losing spark, fuel is there cause it will pop a couple times before it starts again. why would it cut spark? stock ign. coils and .20 on plug gap. before i hooked the vgt up on the turbo it was fine at 21-22 psi but at 26 psi and up it shuts down.

I could try to help ya but id be stabbing in the dark without an updated mod list. boost should of stabilized on a 16g by 5500 rpm and yours spikes like 30 lbs which suggest that the gate needs porting. the tune looks to be a touch lean but without fuel specs i can't really tell.
