My buddy needs soem help

ok my boy has a 05 dodge hemi he put a super chip programmer on it and shortly after he programed it, it blew the 02 sensors. he took it off fixed the 02's programed it again and it blew the sensors again.

I told him he must be running lean and burning them up.

Any suggestions or questions I can throw back at him to get this figured out?

Which 02 sensors, front or back and running it lean will not hurt the 02 sensors but running it rich could foul them or super heat them but this is a first

Blowing the O2's should throw a code. I just blew 2 of mine this past fall and they were intermitant codes but they would definately be there.

He would have a Code.... how else could you know, other than it running a little rough.

What other Mods does his truck have?

I blew both my O2 sensors. Front one made the truck run really rich, you'll notice 'soot' from your exhaust if you don't have a wideband. Rear one did nothing to effect performance, just threw a code.
