After only seeing that 12 psi during that 8.9 run j did some boost leak testing and found that it was leaking past on both sides kf the adapter plate between the throttle body and intake. Given id like to race one more time I disassembled and resealed with some of the grey "right suff" and it seems ro have fixed the leaks I was having. U can see it went from bubbles bubbles everywhere to none. So fingers crossed on the next one she has no more, because I sure as heck could t find anymore.
