That has very little to do with the Knox not working properly
I have changed injectors twice. We checked the cam timing. We checked the turbo put a new turbo on. It's that Knox kit which is a POS. Don't use...
I'm here to tell you it's not the program. We put 15 different programs plus the Knox program in this truck and it makes it worse. It's the kit
Lonox kit will make your truck misfire and run like s*** don't use it
I had mine flashed to the Knox flash and it didn't work. It made it worse
