SuperChip MicroTuner
I installed the MicroTuner today on my wives 7.3L PSD Excursion and am now getting 29 mpg on the interstate going about 70 mph.
Does the tuner run the engine real lean to get this type of mileage and if it is does it cause any sort of damage to the engine?
This thing is totally awesome and I recommend it but I don't understand how it increases the fuel economy so much.
ANyone have an answer?
