67 dart stroker hellcat gen3 hemi with twin turbos...

the car runs well enough i can drive it to and from anywhere. it just randomly stumbles out with a cam sync error of 40+° which would equal massive engine failure if that occured. as cam is huge and pistons are close for comfort. im assuming its sync error.
also assuming ground issue with i/o harness being wrongly pinned from holley or broken wire i cant find or trace to this point
