Default Do I have Magic Injectors?

I replaced my injectors the other day and now my drivers info is screwed up, I filled up and it shows me a range of 550+ miles left and my instant mileage is between 40 and 71 mpg at all speeds and my avg mpg is 42 ...
I reset it and it stills shows the same readings. Did I stumble on a set of super fuel effecient injectors?
How can I fix this.

I would start by pulling the main fuse or disconnecting the battery and seeing if it resets everything.

If that doesn't work - flip the dic switch to "average" then agressively press the "reset" button for that function several times.

Did you put in the same size injectors as original? If not that is your issue. The computer assumes 22lb injectors and determines fuel mileage by using a pulse width caculation. If the pulse width is shortned up because the injectors put out more fuel and the compter uses the O2 sensor to correct for this then the mileage will appear greater then what it actually is. Figure out your real mileage and compare it to your dash reading.

Then they are magic. Keep driving with those things, and challenge a Prius to a mileage shootout.

Sell them to me.

Time to reset your ECM, Disconnect battery, count to ten, reconnect battery, spend an hour reprogramming your radio.

Did you reset everything on the DIC? After that, take it for a drive and see what happens.
