My shorty headers are installed, runs great. New problem is the check engine light is now on and the dealer is telling me that it's the cat converter which I suspected as some type of oxygen/fuel sensor issue. Dealer says they cannot override software to clear and I have to go to a race shop to have new parameters installed to clear. Is there anyone one with a 5.7 with shorty's that can help in clearing the check engine or info that I can respond back to the dealer. Thanks from a frustrated Charlotte NC 5.7 owner!
U need a flash tuner to disable rear oxygen sensors, or you can go to a shop and have a custom tune done there. ive read where some have used spacers and adapters on the bung of the sensors to stop the cel, but others have said it didnt work..tune best route i would think plus tune will unleash some of the power
