Hey looking for a little help to steer me in the right direction. I recently bought a 2010 Camaro SS automatic transmission from a used car dealer. The dealer said it had a lot of aftermarket performance parts put on it by the previous owner and had a tune accordingly. Some of the parts mentioned are Cam, headers, coil overs, spark plugs, and ram air intake. However the car has these codes showing up: P0010 P3401 P219B & P0521. The only issues I can really see from driving the car myself are that it lacks a little in engine performance and it runs really rich. I was wondering if either the tune done to it could’ve caused this or the parts were put on and a tune was never done to it could be the cause of this and maybe I just need to take it to get a tune in the dyno or maybe I need to take it to a Chevy dealership and have it checked and possibly repairs done the check only will cost $170 but the dyno will be roughly $600. I just want the car to run the way it’s supposed to and not potentially cause damage to it driving it the way it is. Please help !?!?

P.S. I’ve already looked up what all these codes mean looked at all components and wiring and see no Visual issues. I’ve done tons of research and watched/read a lot of videos/forums. I also had the oil change done on it at the Chevy dealership and the oil system seems fine. As I stated the only thing I can see wrong myself is lack in engine performance and it runs very rich.

The Chevy dealer likely can't fix it with the cam if it's tune related and it likely is. If it's not the tune, you will spend a lot of money with a dealership because the will likely want to get it closer back to stock. I would work with a good speed shop to sort through the issues. I doubt that taking it to the dealership will cost less than $600 in the end.

Doesn’t look like a tune issue to me. Hopefully you can find a reputable shop to get it sorted out.

Yeah I took it to a tuning shop first and they said that it sounded like there was an issue with the valves and a possible exhaust leak so they didn’t even want to put it on the dyno which I don’t blame them so I have an appointment next week at a speed shop to see if they can figure out exactly what’s going on so I can get it fixed
