The "Tuner" (a person) will make changes to the '7427 fuel tables. The information from the WBO2 can be configured to be in the '7427 data log (recorded engine information when the vehicle was test driven). The data log contains information like, RPM, MAP, TPS, IAC, BLM, INT, and dozens of other parameters.
I saw the picture. I think a good plan would be replace the rear throttle body with a throttle body that has an IAC, (maybe a used Holley Throttle Body) I also think it would be a good plan to upgrade to the new style Holley TBI injectors.
