is that overboost or fuel cutoff. or the a/c code? DG said it,s overboost code. like we didnot know that.still say vac. line off or miss routed

i wound think it,s not electrical cause boost is a vac. contraled. try running streight vac. to waste gate can and it will only make 7 to10 lb of boost.ifline is off it will overboost.i just pulled my motor on my 85 z and the pack of vac. line on the back of the valve cover were tons a cranked or miss installed or broken line will give you over boost
