Turned my truck offin the drive thru so they could hear my order, when I started it back up the check engine light was on. Pulled out onto the highway and had hardly any power what so ever. I barely pulled 15psi on the hx40 and blew no black smoke from the tail pipe. No exceleration at all. It ran perfectly fine before turning it off. What gives? Im guessing comp box is bad or injection pump.

 

dont worry about the quick responce. I took my edge comp off and that was the problem.
