Hello everyone, I have added a zex nitrous kit to my 99 ta. I have a 402 ls2 with a 239/242 cam. I want to spray a 180 shot. I have read that its better to place it after the maf. However I read that after install. I have it before the maf. I know I need to pull some timing before useing the nitrous. Can I get some help on where I would pull timing and how much? I have a wideband installed for doing this. Any info would be great!
