hello everybody.

i drove the car around tonight and from the second i started it till i turned it off i didn't felt the boost at all.
there wasn't any unusual sounds

the gauge shows 8psi's but its barley moving.

i checked for blown charge pipes but i didn't found anything,

the setup is:
log manifold
volvo 760 turbo
turbonatics wg
2" charge pipes
2"dp
apexi twin chamber bov
smic
safc and 450's
stock fpr


what could it be?
