I have a 6.1L Challenger with a manual trans and a Whipple supercharger kit. Otherwise, the engine and exhaust are stock. The STFT+LTFT values for both banks are quite negative (mostly double digits). Neural Network is DISABLED in the supplied tune which is OK by me. I've read that the fuel trims can be adjusted by altering the VE tables BUT I can't find the info on whether increasing or decreasing the VE value in a cell will cause the STFT+LTFT to be less negative (closer to zero). Some help would be appreciated.
