First post, please let me know if this is in the wrong forum.
Little back story bought my 1LT Camaro back in March and really loved it. After visiting this site, I looked into some modifications. I found a couple that I could do but still keep my warranty.

Borla X-Pipes - 60611
Borla Axle-Back Exhaust ATAK - 11927
Tracy Lewis Signature Series – catch can
CNC Ported throttle body – Pray Performance

I had these installed by a mechanic as I have never modified any of my vehicles prior. A day later a check engine light came on. There was also a gas smell at startup. I called the shop up and they said I needed to install anti-foulers. I went back and had them installed by the same shop. This time two days later the light came back on. I had the codes pulled to see what they were.

P2099 - Post catalyst fuel trim system too rich bank 2
P0430 - Catalyst system efficiency below threshold (Bank 2).

I called up the shop again and they are saying that I need to tune the vehicle to remove this. The other idea they gave was to go back to stock throttle body. However, I want some other ideas. I feel like I should not need a tune for these small modifications. I know tuning will void my warranty. This is something that I do not want to do at the moment. The car only has 4900 miles on it.

Please help!
