I’m not a truck driver. But I have a close friend that is. Pete with Paccar. Had truck for several years. Been awesome. Recently lost power while piling a load. Runs fine bobtail no torque loaded. After $11k worth of wiring harnesses, a new turbo, reprogramming (deleted several years back) it’s still not fixed. I ran across a post by spsauerland that caught my attention and there seems to be a wealth of knowledge here and I’m trying to find a way to help him get back to work. Thanks for any…
