You have a vac/boost leak. Boost leak test it. Positive values means ecu is adding fuel to compensate for a leaner-than-expected AFR. In your D range the ecu has pulled fuel in open loop based on other calculations. Any changes you make or made are now being changed by the ecu in terms of open loop fueling. Fix the leaks then reevaluate wideband tuning or else you wont have a consistent AFR. Typically the safe range is 10.4-10.8 for tmic and 11 for a fmic. Its relative to your mods though
