it does ha. i live in iowa and half the year it's too cold to do anything outside. i've got a 68 torino gt i gotta get busy on body work wise (ford i know i know) so i've got plenty to keep me busy this winter though. next year i want to get to the track a lot more. and yea i understand that it's just a recommendation. used to have an even tighter converter in it and it was terrible. so i'm sure if i went looser than 3000 it would only get better
