If I am not wrong, you arethe one with high cams?? High cams...idling sucks. High end...very cun..I've set my adj. to provide low end as I drive an auto and around town alot. If I go track diff. story.Currently, power comes bout 3.4k rpm. Setting is In. pulley 6 degrees retard. Ex bout 2.5 degrees adv. Using stock cams. Always remember the cam turns at half the speed as compared to the crank. So 6+2.5=8.5, I would have reduced 17 degress of overlap.Why? doing so that it will reduce overlap and therefore better low end. (I guess that's how the vvt pulley works). However, high end is not as nice as before...(trade-off).....With high cam, adj. pulley can help compensate your idling problems. And yet still able to provide a much better degree of high end fun.Found out that advancing Ex. will also advance your ignition timing as it is directly connected to the spark distribution. So adv 10 degrees will cause your car to ping like mad. So check ignition timing every time you play with the exhaust pulley.By advancing ex. will also reduce overlap, but you'll soon find out that your ignition timing have a max that you can adj. at the distributor.After some experiment found that the best way to make idling smoother is to retard the IN. and adv the EX.</blockquote>
