hi new on here but ive got an 89 5spd sc had to pull motor to work on it and didnt mark vacuum lines now that ive got it back in supercharger isnt working i think i rebuilt it too it was running close to 16 according to gauge but now it barely gets up to 5 then drops off it isnt whining or anything runs like a n/a 3.8 ported heads, scorpion roller rockers, arp rod bolts, head studs, racer walsh supercharger pulley i think 5%, oem ported manifolds way slower than when i got it with blown head gaskets, and cracked oil pan. 190k miles thanks im guessing and kinda hoping its a vacuum line in wrong spot any help would be awesome.
