taking this off isnt going to throw a code on me, is it. I have every emission mod removed except the FPR, and still have the BAC for now. I have no a/c the power steering isnt hooked up and running the 6th ports by the air pump (makes a turbo swoooshh noise=). my idle is at 1500k at start up and stays there. I have tried EVERY Idle adjustment step

 

The BAC isn't just for A/C and power steering- it's also used for the plethora of electrical loads that pop up during idle. Headlights, e-fan, brake lights, etc...
