calculated fuel economy

What parameters do these trucks use to calculate the fuel economy they display? I am wondering if going to a larger injector would skew this #, even though I don't believe it is highly accurate.

If your tune is set up right the DIC calculation will be close. HP tuners has a bunch of settings for injectors. The injector manufacturer will give you specs to input into the tune. My truck is heavily modified with a cam, headers etc., and my DIC reading is within 5% of my manual calculation
