Engine/Transmission (1998.5 - 2002) computer off or poor mileage with Edge Comp

[jkidd]

Turned on or off (1x1 to 5x5) I seem to be getting 10-20% less fuel mileage on the overhead display. only thing that chaged was removing my Van Aaken to install the Edge Comp? I have not gone through a tank yet, but notice that cruising at 60 the MPG is definately lower on all settings and off.



Is there something I overlooked, or wrong?

I'm pretty sure that the comp screws up the overhead computer.

Just calculate by hand for a couple of tanks to see what the real change is.

All fueling modifications mess with the overhead computer. That thing is calibrated to work with stock fueling only.

yeah you have to do it manualy. when i bought my truck 4 months ago bone stock, 25000 miles, i was getting about 18. 2mpg and when i just have my comp, i always had it on 2x5 i was getting just over 20mpg, a 2+ mpg increase.
