I tow a 10K 5'er. With the Edge on level 3 how important or unimportant is the boost elbow? I have just gotten the Edge and gauges so there hasn't been a tow yet. I am a little concerned about the EGT's and would lik to hear the +/-'s or yes/no's of the elbow. By the way I am a new/old member and this is my first time back since 02' and am I glad to be back!
