Running lean on one of the cylinder banks. Contact Doug.

In the meantime make sure the intake is on secure without any leaks. You probably have a P0171 and a P0174, meaning both banks are running lean. I had these codes when I recently installed my delete plates and a Bamachips race tune. The problem ended up being that Doug accidentally sent me a tune written for a C&L Racer, and I have a C&L Street.

I was worried about it too, I ran mine for a few days with the wrong tune. I asked Doug if I could have caused any damage, and he said that it was fine. My car seemed like it was running fine. I would still get it fixed as soon as you can. I would recommend trying to drive it as little as possible, but if you must drive it take it easy and baby it.
