a few of you has met my friend Leigh and knows the problem he is having with his car. he bought a bov from autoworks and had them install it along with a pod filter. the car shoots out alot of black smoke when the cars in neutral and when driving most of the time there is smoke coming out of the zorst. the bov has been tightened all the way to the end and stil opens at low boost without any surging. when driving up and down the street and coming to a stop the revs dipped once or twice but stopped, but after along drive from beechboro utopia we stopped at a car park to check his oil and it constantly kept dropping until we revved it abit. i know putting the stock one will make the idle problem stop but with the black smoke there seemed to be less black smoke after we tighted it so would this help with the smoke aswell? do you need a tune for a pod filter?
