RE: ISX 870 jake brake issue
Your boost pressure is the pressure of stage 1 jake. What is your max pulling boost pressure?

From the info you've given so far it looks like possibly only 1 solenoid is working. There is a lot of different problems that can cause this with no codes. Rawze listed most of them.
