I have a 99 4x4 dulley with muffler delete, and guages. I just installed the bully dog power pup on the truck and on the 120hp setting the truck will only make 12psi of boost before the programer it made 20psi. I intalled the 70 hp setting and it will make 20psi now, but it is slower than the stock program to build boost and it doesnt feel that much faster. Can anyone tell me whats the problem is this normal?

When I asked that question I was told 70+ HP was all the stock injectors would push.... not sure about the boost question, though?

Sorry I could be any more help.

Does it have the intake air heater? See the blue arrow? Do you have a thing there? If you do then your a late 99
