Hey all. Just finished an HPDE event yesterday at Lightning NJMP. Conveniently, that morning while heading to the track I stopped to fuel up and upon startup I had a CEL. I had my BDX and pulled the code P0430. I cleared the code thinking it was minor and chalked it up to the Steeda tune I recently flashed the car with (only real drive with the tune installed was me driving 2 hours to NJMP from PA the night before). Code did not show up for the entire day and the car ran great but that night heading home from the track, CEL came up again right before getting home.
Again, I'm thinking it might be tune related but I understand it could be coincidental after doing some online research and found catalytic convertor failures are somewhat common for 3rd gen 5.0's (would love anyone's input on this). Car is stock power/components power and drivetrain except for the recent Steeda 93 tune and currently has 26k miles. In the meantime, I flashed the car back to stock and I'm hoping to drive it some this week to see if the CEL comes back.
Thanks all for anyone suggestions and inputs.
