I have changed it and the reading is back! I am running E85. Now I have to figure out why my car is lean. I do have a question though.
I am not doubting my tuner or anything but just want more knowledge for myself. I have recently went down 85mm pulley to a 75mm pulley. My tuner sent me a 1st revision for the drop in pulley. As I compare the old 85mm tune to the 75mm tune, there was no change in fuel, only changes in the flex fuel table. I was expecting some changed to fueling if we are bringing in more air with the smaller pulley but that does not seem to be the case. Would it be possible to add more fuel into the tune to so the car is not lean, or is that not how it's done?
