I have a ford 6.0 diesel. We are putting out about 3 lpm. with NO increase in millage. I have lowered the voltage on the map sensor. We lowered the voltage on the barometer to make the computer think it is higher in altitude. Put a resistor to make the computer think the intake air is hotter than it is. Also put a resistor on the oil temp sensor to make the computer think it is hotter.
All of this has been done one by one 2 by 2 and all at once. We just bought a program to be able to tweak the factory computer. Does any one know what I should tweak on? Thanks in advance.
