89 t2 fuel issue

I installed a bov and the lean condition went away. I'm suspecting a bad stock bypass valve. It still sputters though when it builds boost. It supposedly has a fdc installed,but I haven't checked yet. I looked under the hood and couldn't find any loose wiring. I did change the plugs,but the old ones didn't look bad.

I'm not sure whats going on. I installed the blow off valve and now it goes way rich. The car has an fd fuel pump,could that cause it to go that rich? Do you think it killed my factory pressure regulator? When the rpm increases,the more rich it goes.
