We tuned a customers LMM and ever since the DIC reads incorrect fuel mileage. I realize that these are usually not accurate, however this DIC reads fuel mileage at about 32mpg average! We verified the actual mileage to be about 19 average. What could have caused this by simply tuning the vehicle? We have retraced our steps and can not locate one parameter out of ordinary. Any help is appreciated!
When you modify the fuel table (Injector pulse width), the DIC is no longer accurate.

It is always fun when people think they are getting 25mpg lol.
The DIC reads fine with my tunes
