As for the catalytic converters, if you changed all 4 and they are retail OEM parts then $1200 does not sound that bad to me. Most people on this forum would only run cheap aftermarket converters that would fail after a year anyways so that is why you'll get alot of responses like that.
BBK H pipe with cats are cheap aftermarket? But anyway the tuner shouldnt have damaged anything. Just revert it back to stock and see if it still does it.

2003 V6: Long story short 8k worth of mods. Mostly supporting.
