Your smoothing factor is set to "1", which is always going to show the small erratic jumps you see in those charts. Standard smoothing is "3" and it will smooth out all those ripples. Any and all Z's with a smoothing factor of 1 will look like that. He really needs to hook up a boost controller and check the wastegates both for balance and to make sure they are moving freely and the actuator rods not binding (especially on the passenger turbo). The chart doesn't actually reflect anything out of the normal other than the smoothing factor being set to 1. [ ashspecz.com ] [ agpowers@bellsouth.net ] Enthusiasts soon understand each other. --W.
