I'm down less than 1/4 of a tank since the installation of the Edge and subsequent refueling, and the overhead is reading 3.5 - 4.5 mpg higher than it ever has; Even assuming it is a non-linear increase, I am guessing that this will translate into at least 2 mpg better once the hand calculations are done -
- is this a typical increase?!?! I ran a few days with my foot inexplicably "heavy", but have driven "normally" since the fill-up...

The overhead reads from 18 - 20.5 throughout the year, depending on the ambient / fuel blend, etc., and now I'm seeing 24+...does the Edge screw up the computer calculated mileage that is displayed on the overhead?

Thx / Rauschbo

 

Your overhead is wrong. Hand calculation is the only way to get an accurate reading. Yes, 1-2mpg seems pretty typical for the mileage increase, once you get past the honeymoon stage (Right foot=more fun)

 

- yep, I've know the overhead is off from day one, thus the mention of the hand calculation in my first post; I am assuming, however, that the "offset" inherent in the overhead reading v. actual is at least somewhat first order, and thus the notable increase displayed is indicative of a "real" gain in mpg...

AND - you're right, there appears to be a symbiotic relationship between the force behind the right foot and the smile muscles......

 

Wanna have some real fun unplug the map from the block and feel the power and see the smoke.
did you install the boost elbow?
this only seems to work with the Edge box's

 

I didn't install the elbow, the "manual" indicates it is effective at greater than 20 psi, I've never hit 20 (I am a bbit nervous about going WOT with the stock TC, even with the VB in the tranny)....I've hit 19 psi fairly easily, maybe I should go ahead and run it a bit harder - and start saving for a new transmission?!?

 

Yes, very much so.

An overhead that was dead on before the EZ install will be upwards of 5mpg off after installation.

I'm in the same boat except I don't have the overhead calculations. Last tank I was getting just over 15 mpg (nursing a bad VP44) Just filled up this morning and put the EZ on half way through the tank and got 17 mpg. Can't wait to see what I get after the VP44 gets replaced this weekend.

 

Bone stock I was getting approx 17.5. With the EZ I went up to 19-19.3. I was doing mostly in town driving too. Never did get a chance to stretch her legs. Sold the EZ and went stright back to 17 in a hurry!! Got injectors installed back up to 19. See we don't do it for the performance, we do it for the milage right
