For the reasons stated my MADDOG, return to factory.
NOTE - After you have returned it to factory, IF they hook up for any reason, they may ask you if you have a tuner. :str: THEY CAN'T TELL, and don't let anyone convince you otherwise. What they can tell, is that the PCM has been flashed, and the most logical reason would be if you had a tuner.
What should I do???
Easy! After installing the factory tune and verifying it's OK (take for short drive), disconnect the battery cable to perform a full reset. The cute little code that indicates the PCM has been flashed is gone.
