    E38 Idle Tune

    So I have a 2008 Pontiac G8 GT for right now I am just trying to get my idle tuned as I have not been able to get it out yet because of winter. I have been basing everything off a thread on here about Gen 4 tuning done by BigMike42. I have everything to where the car will start and idle and I can blip the throttle and make spark and tps lock in but my rpm is way to high and I can't get it to come down. If I bring my Airflow Final Minimum down much more the car won't start and when I blip the throttle it'll either die or rpm will fluctuate super bad and then die. What am I needing to adjust to get this right? (Cam specs:229/244 .615"/595" 113+4 with a 3600 stall)
