Awesome. I thought losening the wastegate arm would help. It will get up to 58% at 3500-3700rmp, and then just die off on the watsegate duty. I noticed that it only seems to be doing this when it is cold outside. When it's hott, it has rarely ever cut.... thus also why I was asking Scott for getting a custom map done.... rather have an AP map done than an OpenSource.... but i think the arm does need to be loosen.
