I recently installed BBK long tube headers with a off road H pipe(no cats) on my 2002 Mustang GT(4.6). I put the oxygen simulators on the rear set of oxygen sensors. How do I get my check engine light to go off? Also do I need to tweek the fuel/air mix?

i think you can turn off you rear 02 sensors w/ a tuner

Should I get my own tuner or do I need to go to a shop to do this? Awesome graphics on your reply!
