How Should I Program My Mustang


I have a 2005 V6 mustang and recently put some new parts into it. A K&N air intake, JBA shorty headers,magnaflow high flow catalytic converters, and a JBA dual exhaust kit with an H-pipe. Now I have a flash programmer, but what adjustments should I make to the cars programming? I’ve turned off the rear O2 sensors, but the check engine light still comes on? Thanks in advance!

That’s the only code that comes up, what does it mean though?
