Cruising afr Mustang 3.7 2015
Where do I change the are for idle and cruising? Car has 90 lb/hr injectors, double fuel pump. The car is boosted but my afr's are way too rich at idle and cruising. I changed the flow rate for the injectors and wot lambda for .76.

This car is MAP so you tune fuel trims with speed density. Honestly I never had to change it that much as long injector data is correct - double check that first.
PM me if you want a good boosted tune for S550 V6.
