Boost_Fiend is an unknown quantity at this point
^^^ It will make a difference depending on your o2. I bet its your ecu - o2 combo. You have a black top so you should be running a "fat" o2 and you are running a 63 (redtop) ecu. You will need to swap your o2 sensor for a "skinny" redtop o2. I had the same problem and was using a skinny o2 with a e5 ecu. My wideband would read 11.00 at cruising and idle.
