408 tuning with a Wideband sensor

Drove the Dart to work after lunch today. Seems to be running about the same which is what I expected. It's currently setup with all the Jets that came with the Proform body. As you can see she's very rich while cruising. After work I'm going to adjust the idle mixture screws to see if the idle will lean out with this new body. Then I'm going to enlarge the idle air bleeds .003-.006 to see how that effects it.

Idle = 13.6 - 14.0
40mph cruise 1700RPM 12.0 - 12.5
50mph cruise 2200RPM 12.0 - 12.5
60mph cruise 2600RPM 12.2 - 12.6
70mph cruise 3000RPM 12.4 - 12.8
80mph cruise 3400RPM 12.7 - 13.0
