So I got ahold of BBM and they basically told me the same thing. I am also running that 4bar pressure regulator and all supporting mods for the stage upgrade. I just wanted to be sure that I didn't need to get a new cam for this chip or a new chip for the cam haha

All those problems you list are normal for a Corrado. Just kidding. Fix all the grounds first, then you can start diagnosing the problems. Sometimes fixing the grounds will be the cure. The main grounds to check or replace are: 1: Main battery ground to frame(1xshaunx1’s pic) 2: transmission bolt to frame 3: intake manifold to firewall 4: firewall to hood hinge 5: ground “bus” above relay/fuse box Make sure they are clean, have no crud or corrosion before you bolt them down. Dielectric grease can be used AFTER bolting them down, to prevent corrosion/oxidation. All these grounds are important on older cars as there may be corrosion between the spot welds and mating flanges, reducing current flow to the interior.
