CEL came on and the code reader picked up a P2634 code. I know it has to do with the fuel system. The car runs fine but this is now a permanent code and I can't clear it to see if it reappears. I have an Eforce blower on the car with a custom tune so I'm a little hesitant to have the dealer put hands on it.

Any help from the experts/knowledgeable here?

Thanks

How about if you asked your tuner to clear it, or ask him the best way to do it yourself.

When my c7 set exhaust codes playing around with the NPP flaps, after a few run cycles the light went off all by itself.
