is it possible that an MSD 7 can check out good [by MSD] and fire, but still not work correctly?
my car has lost almost 3/4 of a second. the MSD is the only thing i have not changed. the car still rpms the same, just no power. i have changed or checked a lot of parts. no difference. just slow!

thoughts?
thanks rod in AZ
