just did a swap but im having problems getting any power while in boost. i can drive around ok under 4k just not in boost. i know i am boosting because the bov is going off. however while boosting i hear the bov hissing so i think im leaking boost. i swapped bov's but that did nothing. i checked my vaccum lines and they are fine.

i have a greddy intake manifold and a stock throttle body. i did some searching and people have said the bov vaccum line should go to the top left nipple on the throttle body but i do not have any nipples above my throttle body. WHY!? instead i ran the vaccum line to the nipple on the bottom. from there it runs accross the motor and i have a T with one line to the wastegate actuator and one to the bov. i tryed running the vaccum line to one of the three nipples underneath the intake manifold but that didnt do anything for me either.

can anybody help?! i want power!
