yep its a zz4 cam. i do have a cat, and am using tbi to feed the motor. the tune is not all the way there yet, but i'm hoping to dial it in with the wide band. still got some time before i am due so i'll work on it until then. oh, does anyone know what the driving conditions of the test are? do they just take measurements at idle or do they put it on the dyno? that info would be a big help because then i could work on those specific rpm/map cells.
