MO LS Noobie,
I loaded your bin file and I couldn't get the car to idle, loading with fuel. I am having a sort of similar problem with my tune.. It seems to run very rich. The STFT's are at 129 both sides, but more so on bank 1. The fumes make your eyes water. I checked high and low for vacuum leaks and none. Pinched the booster hose, still no good. If I don't have a vacuum leak,where else would I look? What tables might need adjusting. I have the 8.1L marine injectors and I can't find any data on them. I did not pull them out yet to check their operation with an injector tester to check the spray pattern and to see if they may be leaking, but that would cause the pcm to pull fuel. I changed them because 4 of my stock injector were bad, no fuel flow when triggered. Any ideas?
