I have a 2012 Mustang GT.I had an O/R X pipe with custom tune on my car.I put my stock mid-pipe on with a sct strategy tune with rear o2s cut on to pass inspection I went to get my car inspected after i had driven 80-90 miles and it failed for o2 heater readiness and 02 readiness check. Does anyone know how long it takes to complete this check and is there anyway to cycle through it faster?
