Alright guys, I need your help. I melted the number 2 piston a while back. We rebuilt the engine and put it back in the truck. I put new dragonflow 90 hp injectors in. My fuel pressure seems to be very high, heavy load it showed 25,000 psi. This is with all of the programmers off. It is blowing a tone of black smoke. I figured the smoke would increase but not like this. My turbo is showing 38 pounds of boost on a stock turbo. It just does not seem to run right. I put one of the modules back on thinking it might clean up the smoke a little but it didn't do a thing. It actually seemed to run worse. I found one code, it said low voltage speed sensor? I'm lost, PLEASE HELP! Oh, I already replaced the ECM also.
