There isnot a big lobe at idle with this cam. I'm not sure what the idle is suppose to be but I am running at around 750rpm after warm up and she want's to stall every now and then when I come to a stop. I'm thinking of bumping it up another 50 rpm or so at idle after warm up. Also start up requires just abit more cranking then a stock cam. So far I really like this cam but only time will tell if it's worth it. BTW you guys with 04s+ is there a good high flow fuel filters for our cars?
