So what trans is behind this engine is it a Mack trans? Or fuller! There is a torque limit switch that could be at play here on a Mack trans also ! If there is no check engine light on ! there is something holding back on the power the computer does not see! as joey mentioned grounds and battery / starter connections(top of list) places to start! !
It’s a Spicer 10 speed

Let’s says it not a ground issue… do you know anything about programming problems?

download the svc. bulletin for a 9-2 code and follow the procedures for cleaning the grounds.. I bet you have a bad ground, or even bad wires in the harness, which can be fixed if you find the damaged wire(s).
Any way you can find me a link

So I bought a 1998 Mac CH613 that came with an E7 350 ETEch .
When I bought this truck, it would only boost 12 pounds of boost now I have checked everything as far as fuel pressure my timing sensor I have checked for boost leaks I have checked just about everything mechanically you can think of turbo injectors etc. so I went to the junkyard and got an ECM off a same model truck with the same engine put that ECM on my truck and a Truck started boosting 25 to 28 pounds of boost and I thought that my truck was fixed then after about the fourth or fifth test drive over a period of three days out of nowhere the ECM goes down to 12 psi. So my question is one am I missing do these Ecm need to be programmed? Why would it run good and then out of nowhere run bad
98 E7 350 no power
