Ok, so my shop finally got my turbo installed. We finally got it up and started today, however, It is running way too rich. Has anyone who's gone vpc/afc with an obd1 nat care to help me out with getting this thing tuned. I have all the knobs set to 12 12 12 12 (0clock position) and the dipswitches in the inside are down up down up. At idle the car is just runing incredibly too rich. I'm running 440cc injectors and have a 440cc chip in my vpc. Help!
