I have the code P1248 on my 99 7.3. I get the code from my Supertuner 1705 diagnostics. The code is "Turbo boost not detected". I can hear a more pronounced knock in the engine as of lately. My boost gauge seems to register boost just fine. Does anybody have any idea as to what and where I can begin to start looking at? I have 136k on the clock, Donaldson air intake, Supertuner 1705 set on Tow Safe mode. Any help, pictures, etc. would be greatly appreciated.
