I will drive it for the holidays after they dyno and need about 500 to 800 miles with multiple key cycles so we'll see if my car emits a CEL. I should get it back this Friday.

UPDATE: I had the car over the weekend with the prototype Blackheart Hooker header w/ cats and drove over 500 miles to Indianapolis and back and so far no CEL. I dropped the car back to Holley this morning and I'm back to the Sonic rental
