The juice.

Does the juice with the attitude affect the instant mpg readings on the dash or are these dash readings rendered useless by these power modules?

Thanks.

Rendered useless IMO, but after a few tanks you kind of get the idea of what you are doing. For long freeway runs mine was close, but with multiple accelerations and decelerations it gets weird.

Ahh, are you saying the Juice/Attitude will change or mess with my DIC????

Serious question here, forget the unintentional pun :rolleyes:

ANY box that adds fuel without the knowledge of the ECM will affect the mpg readout...

My 99 Dodge, with the banks stinger plus, no longer is correct but the Excursion with chip is dead on with the display.
