If I got new headers without air for the smog pump and removed it all will i need to a have a chip burned for it to work right or will the ECM be ok with change?

It'll change your emmissions output, but it won't throw a code. So, to answer your question, No.

It shouldn't. Your still running a closed loop system. The computer should make the minor changes that might be required.
