All parts stock besides intercooler and lpfp. Parts in custom tune: XHP stage 3 w/ MHD Catless downpipes PR coils 2 step colder plugs NGK BMP 2.5 fuel pump 5” intercooler Aluminum charge pipe with BOV Never had any issues with the custom tune for almost 2 years, but when trying to go back to stock the car won’t run right. My throttle body suddenly does not want to open wide, not sure if this is due to being thrown into limp mode on startup / pressing gas down, just got a new tmap, charge pipe to intake hose connections (diverter valves) not connected, but if they need to be i need to know. As far as the O2, not sure why they’re shooting up so high, but I do smell a really strong gas smell, but don’t have no exhaust leaks. You can see and compare both the logs to see that the O2s in the tuned log are working properly.
