Default Tuning out rear o2s

I'm kind of new to this and I need to tune out the rear o2s and egr and air what type of scan tool can this be done on? My buddy's shop has a genisys and a determinter scanner also a gm scanner. So my question is can I have him do it for free or do I have to send my computer out for a mail order tune?

Scanners cant permanently change the calibration in the PCM. You need something like HP Tuners, EFI Live, or Tunercat OBD2/JET DST.
