my ses light just came on and it popped the code PO410 secondary air injection system I hooked my predator up to it and thats what it said anyone know what this is and how to fix it I just had some longtubes and ls6 intake installed and got rid of my cats could that be the cause of the problem.

im assuming you deleted the air system when you did your header install. so if you deleted the air system and didnt tune it out the ses will stay on until you tune the air system out.
