Fault codes

I have a 2003 Ford F250 7.3 L. I recently just put an edge chip and cold air intake on it. I keep coming up with fault codes p1280, p1211, p0603, p0705. How can i fix these codes or are they worth worrying about.

Welcome to FTE!
Code explanations available at; Ford OBDII Diagnostic Trouble Codes - Overview .: Articles
The 603 has to do with the keep alive memory module
The 705 is the transmission range sensor circuit showing a malfunction.
The 1280 and 1211 codes I can't find.

Get rid of the Edge chip, restore default tune, and see if the problems are corrected.
