I have been watching my AFR since I recieve my serial cable TAQuickness and noticed that when cruising at 70mph in OD my afr is ~13.8-14.3. That seems to be a little rich and curious what I need to do to lean it out. New to tuning and just finished my first AutoVE of the truck. Truck is a 97 2dr yukon with a 383, marine intake, mild cam and 0411.
