What kind of ignition have you been running? I like to have my modules out of the cone away from the heat

If you can't find a cable, (check dynatek you need the programming software and cable for the 2000i if they are still made). The program is called curvemaker. Without the program, you still have 4 pre-programmed advance curves to choose from. You can use the different curves by playing with the switches and even rotating the ignition to alter those cureves a little:
