2010 5.7 hemi always sets code p0129 after major upgrades
To give you some history. I tuned this vehicle 2 years ago with diablo. This year we just finished major upgrade. Pro charger installed, srt4 map, bbk 90 mm throttle body, holley intake, cai, bosch 550 0280158117 injectors, long tube headers, comp stage 3 cam kit,
the issue im having is when we started the vehicle the throttle warning is flashing, tried relearning according to bbk web site, no avail. called them they said bad throttle body, well 4 throttle bodies later we still have flashing throttle light and check engine light. thats the first issue
the second and bigger issue is the car constantly sets code p0129 for high baro. when i look at engine data map voltage never changes although vacuum does. i've changed the map, its an srt4 one. i have also put in the data from a 2004 srt 4 map sensor as far as offsets go but to no avail. im not a hemi guy but i tune but i can't figure this one out. id sure appreciate any help. i have attached a log file and my tune file and screen shot of the permanent codes.
thank you in advance.
