i just put in my boost and EGT gauges the other night and took it for a ride. The boost would only go to 9psi and that was it. Just to find out if there was a leak in the line to the gauge and to have a little fun we unhhoked the waste gate and corked it and it went right up 31 psi. Is the wastegate more than likely screwed up or am I missing an adjustment. Stock plate FF, AFC FF,and star wheel cranked forward. I did not mess with the smoke screw. This whole diesel thing is all new to me but I have been lurking in the forums and doing searches and have learned alot. Some very informative stuff on here.
