Default figure this one out!!!!!!!!!!!!

i have a 94 12valve 5spd i recently blew a headgasket on it, soooo i figured since i had it apart i would mod it.
i did the kdp fix
quickspool manifold 191dv's 75horse ddp injectors head studs airdog 165 4gsk 60lb springs htt64/71/14 turbo vulcan boots an clamps since i put all this stuff on the truck it will not give it enough fuel to spool turbo, i am only getting a small amount of black smoke i have the timing set at 16* i have checked for boost leaks i have tryed taking out the fuel plate i have pretty much tryed every thing,, what would cause this to happen i am stumped!!!
