I just got mine going today and am starting to adjust them. Right now I just have the exhaust blowing the wastegate open and it tops out at about 45 lbs. I am guessing the bottom turbo is doing most of the work as the gate has the stock 8 lb. spring in it. Can I just adjust boost the the top of the wastegate to control the overall boost ? As the top turbo does more work will the bottom one slow down ? I am going to put a gage on the bottom one this weekend to see what it is doing. Thanks,Gary
