I have about 15 in vacuum at idle and only making about 8 psi boost upto 4000rpm then goes up to about 10 psi till it shifts at just over 5000 rpm, is this normal?
Car seems to be running rich under WOT, black smoke out tailpipe,
What I have done to corrects this is clean MAF and ACT sensors.
Car seems to have less power since exhaust.
What I have is a 90 SC with AOD, stock 3.27:1 gears, stock manifolds, custom 2 1/4" y-pipe with no cats, and factory exhaust from there back, air silencer pulled, high flow panel air filter.
Any ideas?
Thanks
