JB4 shows zero boost
G5 board, finally got it working to change maps after replacing faulty steering wheel buttons. Car feels like it has power, however when boost on fuel or temperature settings are inacted the arrow just stays at 0 the whole time. Inpa shows shadow codes 0X2FCA and 0X2FDA which suggest a coming HPFP failure. When I punch it the half engine picture icon comes on for a couple seconds. SES is never on and there no other codes.
A sprintbooster is also on the car
Why though is the jb4 not showing boost at any rpm range? I don't think the shadow codes above justify the reason. Please help
