New to this; anyway I have a LS3 Camaro with longtube headers with highflow cats, and i had it dyno tuned and the check engine light is still on. it also runs a little rich and bogs a little when you press the gas down... Do yall know what i could do to fix the engine light and bogging? i personally think its the O2 sensors but another thread i saw said the Dynotune should have gotten rid of the light... do yall think i had a bad tune? or do i need to clean O2 sensors/ replace them with stronger ones (if possible)? Thank you for you responces and reading

I would go back to your tuner. They did not do their job. A properly tuned car should not bog or throw codes. At the minimum they should have cleared an codes set during the tune and verified the tune would not throw new codes. You may consider a new tuner as the last tuner appears to not be very good.

Could this cause my cats to fail?

If it continues to run rich, this will dramatically shorten the life of the catalytic converters. I definitely suggest seeking out another tuner to get you fixed up...
