Good Evening folks, i recently started having issues with my z06. So mods are Long tube headers high flow cats, vortex ram air intake and BB bullet exhaust. I got flash tuned in Carlisle 2 years ago by ESC when i got the American racing headers installed. Could changing the axle back exhaust from stock to Bullets cause these codes? I cleaned and re checked the entire intake and MAF and the code went away for about 60miles then the codes showed back up. The car drives normal but i does feel a little underpowered doing a 4th gear pull. Maybe the car just needs to be retuned but i dont know for sure.
