DIC can't be trusted on any tuned car. It can be way off.

Ironically, mine is pretty much right-on since I've modded my car. Before it was consistently about 2mpg off.

Stock cam here with the Edelbrock Stage-1 e-Force. Losing 1 quart of oil every 4000 miles or so (not too bad I guess). Getting 19 mpg city/highway combined. Highway only I'm getting 24-28mpg if I stay at 80mph on average in 6th just cruising. Flat surface at 70mph I get mid 30's. I have the smaller upgraded injectors. I noticed about a 1-3 mpg loss.
